Fixes: https://github.com/shader-slang/slang/issues/7634
Duplicate of PR https://github.com/shader-slang/slang/pull/8052
Primary Changes:
* Added `storeCoherent` and `loadCoherent` for coherent load/store via
pointers. This is backed by `IRMemoryScopeAttr` which is an `IRAttr`
attached to `IRLoad` and `IRStore`
* Logic in `source\slang\slang-emit-spirv.cpp` for load/store emitting
has been reworked to be less messy and more maintainable
* Add to `hlsl.meta.slang` coop vector and coop matrix coherent
load/store operations
Secondary Changes:
* Added a missing load/store test for coop matrix:
`tests\cooperative-matrix\load-store-pointer.slang`

With this PR, MapElement works for the following signatures:
- CoopMat<...>::MapElement(functype(...));
- CoopMat<...>::MapElement(capturing-lambda);
- CoopMat<...>::MapElement(not-capturing-lambda);
- Tuple<CoopMat<...>,...>::MapElement(functype(...));
- Tuple<CoopMat<...>,...>::MapElement(capturing-lambda);
- Tuple<CoopMat<...>,...>::MapElement(not-capturing-lambda);

The user can explicitly use Vulkan memory model, or it will be
automatically used when cooperative-matrix is used.
When vulkan memory model is used, two keywords, "Coherent" and
"Volatile", are not allowed.
There are many differences regarding atomic and texture but
this PR has changes limited to support `globallycoherent`
keyword. When variables with `globallycoherent` is used with `OpLoad`, it
will use additional options, `MakePointerAvailable|NonPrivatePointer`,
that will provide the same effect. For `OpStore`, it will use
`MakePointerVisible|NonPrivatePointer`.

Fixes issue #6898
The -emit-spirv-via-glsl slang-test option has been broken for
some amount of time. Tests that were using it were operating as
if using -emit-spirv-directly, leading to many duplicated tests.
After fixing the test option, there were an number of errors that
appeared as a result.
This change fixes the broken test option and the resulting test
errors. Some of the test errors revealed some legitimate issues,
such as:
-The GLSL bitCount instrinsic only supports 32-bit integers and
requires emulation for other bit widths.
-Emitting GLSL 8-bit and 16-bit glsl integer types did not emit
the proper extension requirements
-Emitting GLSL and casting for 16-bit integers was missing a
closing parenthesis.
-Missing profile for GL_EXT_shader_explicit_arithmetic_types
-Missing toType cases for UInt8/Int8 for the kIROp_BitCast case
in tryEmitInstExprImpl.

CoopMat<T,S,M,N,R>::ReduceRow
CoopMat<T,S,M,N,R>::ReduceColumn
CoopMat<T,S,M,N,R>::ReduceRowAndColumn
CoopMat<T,S,M,N,R>::Reduce2x2
