Vulkan: Implement shader buffers descriptor cache.
Implements a descriptor set cache for UBOs, SSBOs, and atomic counter
buffers. Storage Images and framebuffer fetch input attachments are
not yet included. Requires moving the buffer barrier handling into
ContextVk, similarly to how we handle the barriers for Textures.
The packed description key for the descriptors uses a "fast" vector
with a basic minimum size. For most cases of a few buffers this will
fit easily in stack memory, but for larger programs with many buffers
we fit this into heap memory. The key has a large upper bound due to
the high ES 3.2 requirements and the need to index several values such
as the offset and binding size.
We use dynamic offsets for uniform buffers when possible. This ensures
applications like Manhattan 3.1 that use sets of common buffers with
changing offsets hit the cache most of the time.
Because of resource limits we pick at compilation time whether to use
dynamic or static descriptor sets. Mostly this applies to tests that
use a large number of uniform buffers. A future implementation could
be smart and would recompile the program with heuristics to use a
minimal number of dynamic indices.
Reduces the number of descriptor set updates from ~300 -> ~30 per frame
in Manhattan 3.1 and in Asphalt 9 from 900+ to as low as 0 per frame.

Vulkan: Clean up transform feedback extension pause/resume
1. The xfb counter buffer barrier issued was wrong, following a typo in
the spec. This barrier is now correctly issued using the usual
barrier APIs.
2. A mechanism was added to automatically pause/resume transform
feedback when a program pipeline needs to be rebound. This is
incorrect as it misses the xfb counter buffer barrier. The render
pass is broken instead if transform feedback is active/unpaused and
the program pipeline is changed.
3. The transform feedback counter buffers are now disposed of when
transform feedback is ended. This avoids an unnecessary barrier that
this change would have otherwise incurred (and hence render pass
break) in Manhattan which repurposes the same transform feedback
object.

Add more functionality to BitSetArray class
Add support for more unary and binary operators.
In order to support setLaterBit and resetLaterBit in
BitSetArray::Iterator there were 2 choices -
1. Make a copy of BitSetArray only if it is a mutating usecase
2. Always perform a copy in the constructor
BitSetIteratorPerfTest was run with both patches -
1) Copy only when necessary - RESULT BitSetIteratorPerf.wall_time: run = 116.1067374961 ns
2) Copy always - RESULT BitSetIteratorPerf.wall_time: run = 242.7446459439 ns
We settled on the copy only when necessary path.

Vulkan: Unresolve depth/stencil MSRTT attachments
Using the same shader that unresolves color, this change allows
depth/stencil to be unresolved as well.
In turn, this allows the depth and stencil loadOp/storeOp of the
implicit multisampled image associated with a
multisampled-render-to-texture renderbuffer to be set to DONT_CARE.
Stencil unresolve depends on VK_EXT_shader_stencil_export. In the
absence of this extension, the stencil aspect is not unresolved and must
continue to use loadOp=LOAD and storeOp=STORE. This is not ideal, but
the expected use-case of depth/stencil MSRTT renderbuffers is that they
get invalidated, so that load and store wouldn't happen in practice.

Vulkan: Implement GL_EXT_multisampled_render_to_texture
This change allows the use of resolve attachments in the Vulkan backend.
GL_EXT_multisampled_render_to_texture is implemented using this feature.
The infrastructure for specifying resolve attachments is designed with
eventual support for GL_EXT_multisampled_render_to_texture2 in mind as
well as optimizations to glBlitFramebuffer() and multisampled
backbuffers.
Proper support for glRenderbufferStorageMultisampledEXT is still missing
from this change. All tests use this for the depth/stencil attachment
and don't read back the data. Currently, the depth/stencil attachment
is created as a normal multisampled image.

Fix the crash in angle_deqp_gles31_tests
This crash only happened on a compute test which following a render test.
This root case was that after the render test, mVertexArray11 became an
invalid pointer. However, compute test still went to the common path to
use mVertexArray11. mVertexArray11 is never updated since compute
shader doesn't need to triger DIRTY_BIT_VERTEX_ARRAY_BINDING.
This patch adds checking to avoid compute test to use mVertexArray11.
Besides, more ASSERT checking are added to convenient debugging.

Optimize angle::BitSetIterator.
Adds a new custom bitset template to handle packing as many bits as
possible into a single variable. Intelligently select the right class
depending on platform features and bit sizes.
For now, always use a packed 64-bit set on 64-bit, instead of using
a 32-bit set for smaller bitsets.
