Closes #8112. ~~The issue asks for a "C layout", but in this PR I use
the term "CPU layout" because this naming was pre-existing in the
codebase as `kCPULayoutRulesImpl_`. The primary purpose of this layout
is to match CPU-side struct definitions with the shader side. I'm open
to better naming suggestions, though.~~
Edit: switched back to using `CDataLayout` & `-fvk-use-c-layout`, as the
CPU target depends on the object layout rules of existing CPU layout
rules, but they're incompatible with actual shaders. So a new
`kCLayoutRulesImpl_` was needed anyway.

-Adds semantic SV_VulkanSamplePosition that emits corresponding
gl_SamplePosition and SpvBuiltinSamplePosition
-Adds gl_SamplePosition property to glsl.meta.slang
-Adds SPIRV and GLSL tests for the semantic and property
-Plan is to later implement SV_SamplePosition that follows HLSL range of
-0.5 to +0.5,
and emits GetRenderTargetSamplePosition(SV_SampleIndex) which needs more
complicated IR manipulation for HLSL and Metal
Fixes #7906

* Implement SPV_EXT_fragment_invocation_density
-Adds semantics SV_FragSize and SV_FragInvocationCount and implements them for SPIRV and GLSL using the appropriate target builtins from extensions.
-Adds test case checking for expected target builtins from these semantics.
-For future work, could implement SV_FragSize using pixel shader input SV_ShadingRate for HLSL, and SV_FragInvocationCount needs research.
Fixes #7974

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`.

Closes https://github.com/shader-slang/slang/issues/6805
This change adds a note to the SPIR-V target specific doc that SV_InstanceID does not map directly to SPIR-V's BuiltIn InstanceIndex, and adds a more detailed explanation of the difference, its motivation, and how to derive the actual value equivalent to BuiltIn InstanceIndex with an example.

This change fixes some broken links/anchors in the Slang docs that I found after running a link checker tool on the readthedocs site.
Some of these were broken on GitHub Pages as well, such as anchors with apostrophes or docs that were moved.
The doc writer change adds an explicit .html extension to Parameter links, so that Sphinx/RTD does not treat it as an anchor.
