Vulkan: Reduce pre-rotation spec const to bool
The specialization constant now only dictates whether x and y should be
swapped. The complete 8 possible states of rotation and y-flip are
achieved by using this swap in combination with a driver uniform for x
and y flip.
Swapping is still a specialization constant to avoid degrading
performance of dFdx/dFdy which otherwise would need both to be evaluated
instead of one. On platforms which don't support pre-rotation, the
specialization constant will never change and driver uniforms entirely
govern y-flip. On platforms that do support pre-rotation, only two
variations of the pipeline are needed.

Translator: Make sure built-in variables are consistent
Some transformations left the tree in an inconsistent state, for example
if it used gl_SampleMask from ES3.1+OES_sample_variables and the
transformation added a usage of gl_SampleMask from ES3.2. The offending
transformations are fixed and AST validation is improved to catch such
errors.

Vulkan: Support the single-sampled targets
Add support for gl_SampleMask for single-sampled targets.
When dealing with a single-sampled target, gl_SampleMask
is always be set to 0xFFFFFFFF. And when the target is
single-sampled, sample shading is disabled to enable
Bresenham line rasterization.

Vulkan: Support gl_SampleMask with non-const index
Add support for access to gl_SampleMask or gl_SampleMaskIn
with non-constant index. Replace gl_SampleMask with
ANGLESampleMask and reassign ANGLESampleMask
to gl_SampleMask in the end.
