Vulkan: Retain precision of uniform variables
When gathering in a uniform block, the precision of default uniforms was
dropped.

Translator: Simplify RecordConstantPrecision
Just before ESSL output, this transformation made some constants
specified through temp variables such that their precision can be
specified. This was done in cases where the precision actually affected
the expression being evaluated.
This transformation is simplified by declaring constants more
conservatively as variables, and not stringently attempting to identify
whether that's necessary. This is still not done in trivial cases.
This change is in preparation for another change that overhauls
precision propagation through the nodes. This change removes all
references to TIntermTyped::getPrecision() outside the precision
promotion code itself.

GL: Remove the rewriteVectorScalarArithmetic workaround
This workaround was implemented for a bug in Nvidia driver 387 which is
end-of-life. More recent driver branches (390 and 4XX) are fixed, and
so this workaround is no longer required. The implementation of the
workaround itself could introduce bugs.

Translator: Facilitate integration in FireFox
Instead of relying on is_apple to build workarounds applied on apple
hardware, a new build argument is added for this purpose. This allows
FireFox to more easily include these files in their build system (which
builds every workaround on every platform).
The workarounds are reorganized too and moved from tree_ops/gl/mac to
tree_ops/apple. RewriteRowMajorMatrices is moved there too as it's now
used by both gl and metal. This workaround is large, and removing it
from non-apple builds improves binary size (~40KB on Linux).

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.

Translator: Track nameless interface block field indices in type
Fields of nameless interface blocks are stored as TVariables and
referenced through a TIntermSymbols (unlike named blocks which use
EOpIndexDirectInterfaceBlock with a constant field indices). With this
change, the field index is stored in the variable's type which let's the
TField of the TInterfaceBlock be directly accessible (and not need a
search by name).
This will be helpful in translation to SPIR-V as interface block members
are accessed by field index.

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)
