Store symbol names as a ImmutableString
This will enable compile-time initialization of built-in symbols as
well as reducing copying strings.
Most of the code that deals with names is changed to use
ImmutableString where it makes sense to avoid conversions.
The lexer/parser now allocate const char pointers into pool memory
instead of allocating TStrings. These are then converted to
ImmutableString upon entering TParseContext.

Replace remaining usage of TName with TSymbol
TName used to contain just a subset of the information stored in
TSymbol. It makes more sense to use TSymbol directly instead of
converting it to TName.
This also improves type safety a bit by making some functions only
take in TVariable or TFunction instead of the more generic TName.

Generate performance warnings in HLSL translation
Generate performance warnings for some code that undergoes heavy
emulation when translated to HLSL:
1. Dynamic indexing of vectors and matrices.
2. Non-empty fall-through cases in switch/case.
The warnings are generated only when code is translated to HLSL.
Generating them in the parsing stage would add too much maintenance
burden.
Improves switch statement fall-through handling in cases where an
empty fall-through case follows a non-empty one so that extra
performance warnings are not generated.

Vulkan: Implement basic uniforms.
This implementation adds one descriptor set with two bindings: one for
default vertex uniforms and the other for fragment. It adds two
corresponding uniform buffers, and the logic for updating the
descriptor sets bound to Vulkan. It doesn't handle much in the way of
synchronization and dependency management, or uniform update.
If there are only vertex or fragment uniforms the empty uniform buffer
is omitted from the descriptor set. If both are missing, there is no
descriptor set bound.
Note that as our implementation progresses we might not be able to
initialize our descriptor sets at link time, due to streaming in
uniform data.

Vulkan: Implement basic uniform shader parsing.
This is a first step at implementing uniforms with descriptor sets.
It does not actually bind uniforms and upload data, but it does
implement uniform shader parsing. Uniforms are gathered into a single
uniform block which is bound to set 0, with binding 0 for vertex
uniforms and binding 1 for fragment uniforms.
Also adds a ReplaceSubstring helper to string_utils.
Also removes the precision writing from OutputVulkanGLSL since this
was generating warnings with glslang.

Vulkan: Implement new GLSL translator back-end.
The Vulkan GLSL translator back-end will handle validating and
translating our WebGL/ESSL shaders into Vulkan-specific GLSL.
glslang (the Vulkan one) accepts both GLSL and GLSL ES shaders
as inputs, and both the desktop and ESSL back-ends give
incompleteness warnings when used. For now, use the desktop GL
450 as a target for Vulkan GLSL.
The Vulkan-specific changes are currently only to add locations
to every vertex input and fragment output.
