Don't use TIntermSymbol nodes for function parameters
Parameter nodes are not needed - it's simpler to just create a
TVariable object for each parameter when the TFunction is initialized.
With this change we also store only one object per each parameter type
used in built-in functions, instead of one array of TConstParameter
entries for each unique parameter sequence.
This simplifies code and reduces binary size and compiler memory use.
Compiler perf does not seem to be significantly affected.

Clean up ValidateMaxParameters
It doesn't need to use a traverser, since all function definitions can
be found simply by iterating over the children of the root node.

Always store function headers in TIntermFunctionPrototype nodes
TIntermFunctionDefinition nodes now have a TIntermFunctionPrototype
child that stores the function signature, instead of having a separate
type and an aggregate child that stores the parameters.
This makes parsing functions simpler, and paves the way for further
simplifications of function parsing, like reducing conversions between
symbol table structures and AST structures.
TIntermAggregate is now only used for function calls.

translator: Scope all classes with "sh".
I was seeing an odd problem with our PoolAlloc conflicting with the
glslang/Vulkan TIntermNode, so the fix was to move everything to a
separate namespace.
The bison grammars are also regenerated. No functional changes.

Add option to limit the number of function parameters
Trying to compile user-defined functions that have thousands of
parameters introduces some instability in native compilers, so it is
better to reject shaders with large numbers of function parameters
in ANGLE.
The check is only enabled if the SH_LIMIT_EXPRESSION_COMPLEXITY flag
is turned on. The default limit for the number of parameters is 1024,
but it can also be configured.
