metal: adds feature that minimizes generated shader differences
This adds a feature (enabled by default) that results in
generating the same code regardless of whether emulateAlphaToCoverage
is enabled or addExplicitBoolCasts. This is done to maximize
cache sharing.

Metal: Implement OES_shader_multisample_interpolation
* Added support for sample qualifier
and shader interpolation functions
* Added MSL-specific AST transformations
* Adjusted minimum fragment interpolation offset state
query test so that accurate limits could be reported
* Drive-by: Y-flip gl_SamplePosition adjustment
* Renamed ANGLESampleMaskEnabled function constant to
ANGLEMultisampledRendering to correctly reflect its
usage

Metal: Implement OES_sample_variables
New ESSL built-ins are mapped to their Metal
counterparts and tweaked to follow OpenGL ES
semantics when needed.
Fixed A2C interaction with sample coverage
by emulating the former on non-Apple GPUs.
