bdfa97a1cf Unify vertex clip-coord fixups. 
The different options were scattered around in different backends and
didn't really work right with CLI at all.

2abdc135c3 Declare undefined values up front. 
They might potentially be used as part of OpStore in the SPIRV-Tools
inliner in some cases.

Implement these as declared variables but without any initializer.

b41e1482c8 Support emitting SPIR-V type declarations tuned for specified SPIR-V objects. 
CompilerGLSL type_to_glsl() and image_type_glsl() functions support optional object ID.
Add SPIRType::Image::access member to support SPIR-V OpTypeImage access qualifier.
Remove SPIRType::Image::is_read and ::is_written members.
Use DecorationNonReadable and DecorationNonWritable to mark read/write access for image variables.
CompilerMSL emit access qualifiers per image variable, instead of per image type.
CompilerGLSL and CompilerHLSL behaviour is unchanged.

3f74503aca Prefer plain texture2D in legacy es vertex shaders 
WebGL supports lod texture funcs only in fragment
shaders but SPIR-V supports only lod texture funcs
in vertex shaders. This reverts calls which were
forced (infered from using a 0 constant) to use
an lod to plain calls in vertex shaders when
using legacy es.

ed04c95b08 Implement flattening of row major matrix indexing 
To extract a column from row-major matrix, we need to do a strided load one
component at a time. In this case flattened_access_chain_offset still returns
the offset to the first element, but the stride is equal to matrix stride
instead of vector stride.

For this to work, we need to pass matrix stride (and transpose flag) through,
similar to how matrix flattening works.

Additionally slightly clean up recursive flattened_access_chain structure -
specifically, instead of deciding mid-traversal that we need matrix stride
information, we can just pass the matrix stride through - for access chains
that end in matrix/vector this gets us what we need, and for access chains
that end in structs the flattened_access_chain_struct code will recompute
correct stride/transposition data to pass through further.
