Reland "Vulkan:Include precision qualifier in GLSL"
Currently still ignoring precision qualifiers for Vulkan shaders by
default, but have added feature "enablePrecisionQualifiers" that can be
enabled in order to include precision qualifiers.
With this initial implementation, it's possible to get precision
qualifier mis-matches in the generated GLSL 4.50. According to the
spec this is allowed. From GLSLangSpec 4.50 section 4.7 "Precision and
Precision Qualifiers":
For the purposes of determining if an output from one shader stage
matches an input of the next stage, the precision qualifier need not
match.
However, when converted to SPIR-V and run through the shader validation
any mismatches will cause shader validation errors. Initially just
ignoring those errors with this commit.

Revert "Vulkan:Include precision qualifier in GLSL"
This reverts commit 93e72f5f0eb80b89334ea8fe577b32901a00b5fb.
Reason for revert: This is having a negative impact on gfxbench
Manhattan 3.1 tests (20-30%) with only a minor improvement (~4%) in TRex offscreen. Pulling out for now and need to re-evaluate best
solution here.

Translator: Memory qualifiers on SSBO fields
These were not output prior to this CL.  Of these qualifiers, readonly
and writeonly are unnecessary as ANGLE already does the appropriate
validation, but the rest (coherent, volatile, restrict) are necessary,
even though the tests pass on the bots by coincidence of driver
behavior/test simplicity.

Vulkan: EXT_gpu_shader5 support: precise
The precise keyword is used in tessellation shaders but introduced in
this extension.
EXT_gpu_shader5 introduces a handful of features to shaders.  This
change only implements the `precise` keyword.
