Translator: Be more explicit about precisions
GLSL ES requires that every symbol (variable, block member, function
parameter and return value) is appropriately qualified with a precision,
either individually or through the global precision specifier.
Some tree transformations however produced symbols with EbpUndefined
precision. In text GLSL output, these would produce unqualified symbols
which was often incorrect.
In this change, the transformations are made to produce explicit / more
consistent precisions. The validation (that caught these issues) is not
included in this change as there are still a few corner cases left to
address.

Translator: Clean up type cloning
TType has a constructor that aids cloning + helpers to convert between
types. A number of places where a type is constructed from the
information gathered from another type is changed to clone the type and
then use one of these helpers.
This clean up is part of an ongoing work to improve precision handling.
This change removes many references to TType::getPrecision().

Translator: Validate function parameter qualifiers
This change cleans up a confusion in EvqConst and EvqConstReadOnly,
where the former was frequently used instead of the latter for function
parameters.
The change makes the following renames to make the intent of the
relevant qualifiers clearer:
EvqIn -> EvqParamIn
EvqOut -> EvqParamOut
EvqInOut -> EvqParamInOut
EvqConstReadOnly -> EvqParamConst

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.

The functions that take a TIntermSequence always copy out / Swap the
contents away. This change makes all TIntermSequences live on the stack
instead of being newed.

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)
