Clear11 Shader Optimizations and Shader Management Rework
- ClearShader made into a class that manages all required shaders and input layouts for clears
- ClearShader reuses VS for all clear types. This reduces shader compilation time and memory usage
significantly
- Use constantBuffer for color/z values instead of VB to decouple VB & VS from clearType and
allowing for the same VS to be used for multiple clear types
- FL10+ Devices: Generate positions using SV_VertexID in VS to avoid having to bind VB.
- FL93 Devices: Use an immutable VB containing only position data (SV_VertexID not supported)
- Implement CB cache. Incoming color/Z values checked against cache and CB/cache only updated if
there is a mismatch. Significantly reduces the frequency of expensive CB map/rename operations
especially in common scenarios where most/all clears use the same color/z values

Enable MSAA for texture client buffers
Enhancement to the EGL_ANGLE_d3d_texture_client_buffer extension to
allow use of a shared D3D texture that can be multi-sampled.

Revert "D3D11: Clean up blendState code."
This reverts commit 786ad3876730c72311c64cf2f297e671ced847a5.
Reason for revert:
Seems to have a bug with binding the BlendStates, causing a crash on
Intel.
https://luci-milo.appspot.com/buildbot/chromium.gpu.fyi/Win10%20Release%20%28Intel%20HD%20530%29/141
Failing WebGL 2 tests
WebglConformance_conformance2_reading_read_pixels_from_fbo_test
WebglConformance_deqp_functional_gles3_readpixel
Also generates D3D11 runtime warnings:
D3D11 ERROR: ID3D11DeviceContext::Draw: The renderTarget bound to slot 0 has a format (R8_UINT) that does not support blending. The Pixel Shader output signature indicates this output could be written, and the Blend State indicates blending is enabled for this slot. [ EXECUTION ERROR #376: DEVICE_DRAW_OM_RENDER_TARGET_DOES_NOT_SUPPORT_BLENDING]

> D3D11: Clean up blendState code.
>
> Masked Clear Draw Changes:
> - Use universal blendstate object
> - Eliminate blendState cache for masked clears
> - Use rasterState and scissor rect for scissoring instead of adjusting vertex positions
> - VB contains only static position data (per vertex color removed)
> - Clear color(s) and depth clear values now passed in using a constant buffer
> - MultiColorclear shader used for float clears to workaround alpha rounding issues
> - Update shader compile script and shader source and bytecode headers
> - Remove unused shaders (source and bytecode headers)
> - Use com pointers where possible for D3D11 objects

D3D11: Implement multisample depth resolve.
This uses a pretty slow path with readback to the CPU. It should be
possible to use SV_Depth in HLSL to resolve without a readback, but
that will be left for a future optimization.
Enables the WebGL 2 tests gles3/fbomultisample and fboinvalidate/sub.

D3D11: Implement multisampled stencil resolve.
This implements a fairly slow path with readback for stencil blits,
and depth/stencil resolve. In a subsequent patch I'll implement the
depth blits.
