Translator: Ensure structs and blocks are uniquely defined
A new AST validation is added to ensure that the same TStructure or
TInterfaceBlock is not redundantly defined. This helps with SPIR-V
generation by allowing the id to be used as key in a hash map that looks
up the corresponding SPIR-V type id.
A bug is fixed where the Vulkan driver uniform declaration created two
identical declarations for ANGLEDepthRangeParams.
A number of other bugs are also fixed in this change, where if a
variable declaration is eliminated (for example due to constant folding,
or inactive interface variable removal) and it contained a struct
specifier, the struct declaration was also removed. OutputGLSLBase had
a hack where structs were declared on first encounter, which was
incorrect as the scope of the declaration could change. Those bugs are
fixed and this hack is removed.

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)
