Vulkan: break dependency to the depthClamp feature
Image clear's masked clear path using a draw call was using this feature
to clear the depth buffer, but this feature is not available on ARM and
some Qualcomm devices.
This change adds a push constant to the vertex shader used in this call
to export the depth clear value, removing the need to rely on depth
clamping.

Vulkan: fix masked stencil clear
Previously, masked stencil clear was done by clearing every stencil bit
to the ClearValue & Mask. The correct behavior as implemented in this
change is to clear only the bits that are set in Mask. This can only be
done through a draw call, with ClearValue as the stencil reference, and
Mask as the stencil write mask.
Note: this change relies on the depthClamp Vulkan feature which is not
available on ARM.

Vulkan: fix non-float clear with draw
Instead of using one draw call that clears all attachments, multiple
draw calls are issued that clear a single attachment each. This allows
us to have a manageable number of variations for the ImageClear.frag

Vulkan: glClearBuffer* implementation
Refactors FramebufferVk::clear such that specific render targets could
be cleared, with clear values not necessarily set through glClearColor
etc.
FramebufferVk::clearWithRenderPassOp is modified so that loadOp and
clear values are set after the render pass has been registered in the
graph. This allows multiple glClearBuffer calls to coalesce into the
same render pass.
glClearBuffer calls are then implemented simply as calls to the
refactored clear function with the appropriate parameters.

Created new specialized commands for updating Compute/Graphics

Vulkan:Optimize SecondaryCommandBuffers
RELAND of this commit. Had to fix fuzzer build errors.
Optimize performance of SecondaryCommandBuffers and enable them as the
default build option.
To disable this set angle_enable_custom_vulkan_cmd_buffers=false in
your build args.
This CL enhances the PoolAllocator to have a "fast" mode that can
be enabled at class creation. This mode uses an alignment of 1 byte and
enables a fastAllocation() call that avoids some bookkeeping overhead.
The SecondaryCommandBuffer uses this fastAllocation() function.
Furthermore the fast path of fast allocate, using the current page,
is inlined for maximum speed.
Jamie Madill also updated the SecondaryCommandBuffers to pre-allocate
blocks so that the commands occur linearly in memory. This speeds up
processing with improved cache coherency and minimizes overhead when
recording commands.
Also the core Draw functions and their state updates are all inlined
as well as the common functions to initialize commands and to copy
command pointer data.
This change also includes some new, custom commands. One is
imageBarrier that is a specialized version of pipelineBarrier that only
performs a single image layout transition.
There are customized versions of various Draw commands to minimize
copying of parameters.
There are also specialized commands to bind[Graphics|Compute]Pipeline
that have the pipeline type built in to the command.
More custom commands and command data size optimizations will be made
in follow-on commits.

Integrate the custom SecondaryCommandBuffer type into the CommandGraph
nodes by adding new ANGLE_USE_CUSTOM_VULKAN_CMD_BUFFERS define that can
be set in the BUILD gn args with angle_enable_custom_vulkan_cmd_buffers

Initially the custom cmd buffers are disabled by default.
This adds some support functions to SecondaryCommandBuffer to make the

Vulkan: optimize image memory barriers
Each image was tracking its current layout, but not the pipeline stage
it was used. Additionally, the barrier access masks were inferred from
the layout. This incurred two inefficiencies:
- The src pipeline stage mask often included all stages, causing
unnecessarily heavy barriers.
- The access masks included all possible accesses by a layout, which in
some cases was overkill, like VK_ACCESS_MEMORY_WRITE_BIT for
VK_IMAGE_LAYOUT_GENERAL (which will eventually used for compute shader
output).
This change instead creates an enum where each element represents the
layout, the stage and access masks when transitioning into the layout
and the stage and access masks when transitioning out of that layout.
The image will instead track a value of this enum (instead of
VkImageLayout), which allows it to create the layout transition barriers
as tight as possible, since it includes all the necessary information.

Vulkan: Store reference to context command buffer.
This frees us from checking the FB every draw. Slightly reduces time
spent in all draw methods. Improvement seen on the draw call overhead
tests. Scores went from 28.17 ns/draw to 26.76 ns/draw on my machine.
In a future improvement we could make this command buffer a dirty bit.
Currently it's a bit slower to call a handler function due to the
dispatch table. Likely we could optimize this by reverting back to a
dirty bit switch and inlining the handler functions. That is left for
future work.
Vulkan is happy enough to run multiple RenderPasses and bind different
Pipelines in the same command buffer. But ANGLE defers RenderPass init
until we submit our work. Thus we can only support one RenderPass per
secondary buffer.

Vulkan: More Vertex Array optimizations.
Inlines a number of Vulkan vertex array methods.
Also changes the way vertex buffers are bound. Note that Vulkan doesn't
support NULL buffer bindings. Thus we create an emulated NULL buffer
to work around the problem of having gaps in the bound vertex buffers.
This allows us to use a single bind call for ranges of vertex buffers
even when there are gaps.
Also changes how vertex array dirty bits are reset. Instead of calling
memset to clear the affected buffers we pass a mutable pointer to the
Vertex Array sync state. This allows us to only reset the dirty bits
that we sync. This saves on the memory clearing time.
Improves perf by about 10% in the Vulkan VBO state change test.

Vulkan: Put viewport and scissor back in pipeline desc.
Turns out this is much faster than using dynamic state. When we
support multiple viewports it might be easier to use dynamic
state since we won't need to make an overly large pipeline
description. We could support both methods using a flag to
indicate the viewport and/or scissor regions are invalid.
Until then we can remove the pipeline and scissor dirty bits.
Improves perf by about 15% in the Vulkan VBO state change test.

Vulkan: Faster state transitions.
Implements a transition table from Pipeline Cache entry to
state change neighbouring Pipeline Cache entries. We use
a 64-bit mask to do a quick scan over the pipeline desc.
This ends up being a lot faster than doing a full hash
and memcmp over the pipeline description.
Note that there could be future optimizations to this design.
We might keep a hash map of the pipeline transitions instead
of a list. Or use a sorted list. This could speed up the search
when there are many transitions for cache entries. Also we could
skip the transition table and opt to do a full hash when there
are more than a configurable number of dirty states. This might
be a bit faster in some cases. Likely this will be something we
can add performance tests for in the future.
Documentation is also added in a README file for the Vulkan back
end. This will be extended over time.
Improves performance about 30-35% on the VBO state change test.
