Vulkan: Pack driver uniforms
Previously 5 vec4s were used for driver uniforms + 2 vec4s if
specialization constants couldn't be supported.
The driver uniforms are rearranged and packed such that only 2 vec4s are
normally used, which include fallback for specialization constants as
well. In the future, most of the specialization constants may turn into
uniforms, and this change prepares for that.
Additional uniforms are used (3 vec4s) only if common extensions are
missing; transform feedback and bresenham lines.
This change makes it more practical for driver uniforms to be turned
into push constants. Additionally, these uniforms could potentially be
loaded and cached at the beginning of the shader for more efficient
memory access.
On Pixel6, with this change, the traces show no difference in wall time.
On most traces, CPU time shows up to ~7% improvement.

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: Generate Ops for all built-in functions
EOpCallBuiltInFunction is removed in this change, as well as the
"op": "auto" property in builtin_function_declarations.txt. Instead,
gen_builtin_symbols.py automatically generates Ops for every built-in
function and generates the TOperator enum accordingly.
This simplifies SPIR-V code generation by allowing switches to be used
on operators instead of string comparisons.

Upstream Apple's direct-to-Metal backend: compile translator.
This change is meant to merge the translator changes from Apple's
direct-to-Metal backend. Taken from Kyle Piddington's CL:
https://chromium-review.googlesource.com/c/angle/angle/+/2857366/
The goal of this CL is to merge the translator code in a state that
compiles, but not to switch the Metal backend over to use this
translator backend yet.

Organize AST transforms per backend
Most of the AST transforms are written as a workaround to an issue that
affects a single backend. This change identifies such transforms and
organizes them by backend. They are then only built if the respective
backend is.
Additionally, about half of the GL transforms are due to mac
workarounds, including the large RewriteRowMajorMatrices transform.
Mac-specific workarounds are additionally only built on said platform.
This change reduces the ANGLE binary size:
- 106KB in a Vulkan-only build on Linux
- 27KB in a GL-only build on Android (60KB on Linux)

Revert "Vulkan: Remove rotation related data from driver uniform"
This reverts commit fd97c3343e9ff23677124b7528ec945bca65796a.

performance regression with older qualcomm driver. We need to keep the
driver uniform code path for the older driver.

Disable shader's pre-rotation code on Metal & non-Android.
Pre-rotation code were added to transform gl_Position, gl_FragCoords,
gl_PointCoords, dFdX, dFdY in shader. However, it is only useful for
android's surface pre-rotation and completely un-needed in Metal
back-end.
This CL disables these pre-rotation code if the platform is not
android.

Translator: Allow tree validation in children of TCompiler
This is to be able to perform validation inside TranslatorVulkan, even
if it's through ASSERTs.
Additionally, every transformation is changed such that they do their
validation themselves. TIntermTraverser::updateTree() performs the
validation, which indirectly validates many of three tree
transformations. Some of the more ancient transformations that don't
use this function directly call TCompiler::validateAST.
