Vulkan: Move renderer to namespace vk
This class is agnostic of EGL. This change moves it to namespace vk for
use with the OpenCL implementation

Vulkan: Cleanup ContextVk::hasStartedRenderPass APIs
ContextVk has a few hasStartedRenderPass APIs which interpret "start"
inconsistently. A RenderPassCommands' life should be notStarted,
started, requestEnd, and end (which is equivalent to notStarted). When
someone calls onRenderPassFinished on a started renderpass, it does not
immediate endRenderPass, but it will set DIRTY_BIT_RENDER_PASS dirty bit
so that next draw call will trigger endRenderPass and start a new
renderPass. We do not have a name for this state, which adds some
confusion. This CL renames the stage between start and
onRenderPassFinished to be "active" renderpass, when you have
mRenderPassCommandBuffer pointer being valid and you can actively adding
draw commands into the renderPass. For this purpose, I haves renamed
hasStartedRenderPass to hasActiveRenderPass. This CL also simplifies
hasStartedRenderPass implementation to only check
mRenderPassCommandBuffer and turned mRenderPassCommands.started as
assertion. This CL also changes hasStartedRenderPassWithQueueSerial to
actually check mRenderPassCommands.started instead of being "active", so
that name reflects what it is actually checking. This CL also changed
hasStartedRenderPassWithCommands to hasActiveRenderPassWithCommands to
make name and implementation consistent. One added benefit of this is
that after this CL we now allow load/store optimization on a started but
inactive renderPass as well (for example glInvalidateFramebuffer call
after glFenceSync call, or invalidate after FBO blit as demonstrated by
MultisampleResolveTest.ResolveD32FSamples tests).

Vulkan: Make ResourceUse::serial an FastVector of Serials
In preparation for per context queue serial, this CL makes
ResourceUse::serial a FastVector of Serial. Right now we still limited
to one serial index so that it still work the same way as before. This
CL adds necessary data type and change the function names to reflect
that tracking GPU progress needs a ResourceUse object instead of a
single Serial number.

Vulkan: Distinguish RP and outside-RP command buffer types
What goes inside and outside a render pass command buffer is largely
mutually exclusive. Moreover, the size and frequency of allocations is
different between the two.
This change distinguishes the C++ types used for inside and outside
render pass command buffers:
- The type now documents which command buffer a function is able to
receive.
- `isRenderPass` flag passing, checking and asserting is largely
removed.
- A follow up change experiments with using different (Vulkan vs ANGLE)
secondary command buffers for inside and outside RP command buffers.
- A future change could specialize the pool behaviors per command buffer
type.

Vulkan: Support PrimitivesGenerated query
This query uses the Vulkan transform feedback extension. In GL,
GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN and GL_PRIMITIVES_GENERATED
queries can be independently begun/ended. However, Vulkan requires that
queries from pools of the same type can only be active one at a time.
This forbids the two GL queries from being handled by two VK queries
when they are simultaneously begun.
This change makes these queries share their QueryHelper objects. The
Vulkan transform feedback queries unconditionally retrieve both results
anyway, so this is just a matter of making sure the two GL queries are
merged as one when they are simultaneously used.
The change fixes a number of issues as collateral:
- TransformFeedbackPrimitivesWritten queries when !emulated were not
released
- Stashed queries were never released
- If no render pass is open when a query ends, then getResult(no_wait)
ended up waiting

Vulkan: Fix incorrect reordering of barriers
Take the following situation, a simple copy from image to buffer:
ANGLE_TRY(contextVk->onBufferTransferWrite(buffer));
ANGLE_TRY(contextVk->onImageTransferRead(aspectFlags, image));
CommandBuffer &commandBuffer = contextVk->getOutsideRenderPassCommandBuffer();
commandBuffer.copyImageToBuffer(imageHandle, layout, bufferHandle, 1, regions);
Both `onBufferTransferWrite` and `onImageTransferRead` may flush either
the outsideRP or insideRP command buffers. If buffer is not previously
used, but image is used:
- onBufferTransferWrite: buffer usage is recorded in outsideRP1
- onImageTransferREad: outsiderRP1 is flushed, outsideRP2 is started
- copyImageToBuffer: recorded on outsideRP2, but buffer usage not
recorded there
- A following command that uses the buffer and requires barrier doesn't
close outsideRP2 as it believes it was not used there

Vulkan: Remove dead path in clear
If the clear is not mid render pass, clearWithLoadOp was used to either:
- modify the current render pass loadOps, assuming no rendering has been
done, or
- defer the clears by staging them in the attachment images.
The former path however is dead code. It's impossible to start the
render pass without recording any commands. In other words, if the
render pass has already started, the clear must be mid RP.

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.
