Vulkan: Support OES_sample_variables extension
Enable OES_sample_variables extension on Vulkan backend.
Add support for built-in variables, uniform state and constants
- gl_SampleId, gl_SamplePosition, gl_SampleMask,
gl_SampleMaskIn
- gl_NumSamples
- gl_MaxSamples
Bug: angleproject:3588
Tests: dEQP-GLES31.functional.shaders.sample_variables.*
KHR-GLES31.core.sample_variables.*

Revert "Vulkan: Remove rotation related data from driver uniform"
This reverts commit fd97c3343e9ff23677124b7528ec945bca65796a.
Reason for revert: The specialization constant for rotation causes
performance regression with older qualcomm driver. We need to keep the
driver uniform code path for the older driver.
Original change's description:
> Vulkan: Remove rotation related data from driver uniform
>
> Rotation is now handled in the shader compiler with specialization
> constant, it should be removed from driver uniforms. Since Metal is
> using the flipXY, flipXY/negFlipXY are still kept in the shader side
> implementation, but have moved to TranslatorMetal in this CL.

Rotation is now handled in the shader compiler with specialization
constant, it should be removed from driver uniforms. Since Metal is
using the flipXY, flipXY/negFlipXY are still kept in the shader side

Vulkan: Factor out DriverUniform code to tree_utils/DriverUniform.cpp
The driver uniform code is used by various tree_ops functions. But all
driver uniform code are defined and implemented in the
TranslatorVulkan.cpp file. There is dependency rule that tree_ops code
can not call into vulkan specific function. Right now we are working
around this problem by always having TranslatorVulkan creates uniform
and pass it down to tree_ops. This creates inefficiency for cases that
dFdy/dFdx where we don't know if we will need the driver uniform or not,
until we walk the tree and see the dFdx node. This CL refactors driver
uniform code into its own file and class under tree_utils so that
everybody can use. Mean time we can also make it much easier for metal
to expand it to have its own uniform structure.
