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.

into H2 (#6986)
readthedocs treats H1 headings as document titles in the sidebar table of contents.
This change turns all extra H1 headings into H2 in the "Metal-Specific Functionalities" doc.
These extra H1 headings seem to be errors, given that they are inconsistent, and the H2s after them do not belong. For examples, the heading "Resource Types" is H2, but "Array Types" is H1, and "Mesh Shader Support" is H1, but the following "Header Inclusions and Namespace" is not a subtopic of the Mesh Shader Support.

Change modifies the countbits intrinsic to use generics in order to
support 64bit countbits on select platforms where this is supported.
On platforms where this is not natively supported, we emulate by
converting the 64-bit type into a uint2 (metal and spir-v).
This should align with the implementation of other uint64_t
intrinsics such as abs, min, max and clamp.
Added new countbits64 test to verify changes.
Updated documentation for 64bit-type-support.html

* Document matrix multiplication operators
This is to address one of cases where a user was confused about why
Slang doesn't have operator overloading of multiplication for matrices.
It is little confusing that glsl.meta.slang implemented `operator*()`
for matrices but Slang/HLSL doesn't. It turned out that HLSL/Slang
performs a component-wise multiplication with `operator*()` whereas GLSL
performs a matrix multiplication.
* Mentioning CUDA
* Update based on the review feedback

* Remove support for ad hoc Slang IR compression
This change is part of a larger effort to clean up the approach to
serialization in the Slang compiler. The overall goal is to simplify
and streamline all of the serialization-related logic, so that we are
left with code that is less "clever," and easier to understand for
contributors to the codebase.
Removing support for compression of serialized Slang IR has
benefits that include:
* Reduction in code complexity: consider things like the subtle way
that the `FOURCC`s for compressed chunks were being computed from
the uncompressed versions, and the mental overhead that goes into
understanding that, for anybody who would dare to touch this code.
* Reduction in testing burden: there have been, de facto, two
very different code paths for serialization of the Slang IR, and
it is not clear that the existing test corpus for Slang has
sufficient coverage for both options. By having only a single code
path, every test that performs any amount of IR serialization helps
with test coverage of that one path.
* Opportunity to explore alternatives. This is perhaps a reiteration
of the first point, but once the code is stripped down to the
simplest thing that could possibly work (I am not claiming it has
reached that point yet), it becomes easier for contributors to
understand, and it becomes more tractable for somebody to come along
with an improved approach that performs better (in either
compression ratio or performance) while still being maintainable.
In my own local setup, I found that removing support for Slang IR
compression led to the `slang-core-module-generated.h` file increasing
in size from 46.1MB to 47.4MB. This increase in the `.h` file size
for the core library binary only resulted in a release build of
`slang.dll` increasing from 20.0MB to 20.2MB. Removing the ad hoc
compression support has almost no impact on the size of actual binary
Slang modules *so long* as the additional LZ4 compression step is
being applied to them.

Improve performance when compiling small shaders.
Avoid copying witness table entries that are not getting used during linking.
Avoid copying auto-diff related decorations and derivative functions during linking, if the user modules doesn't use autodiff.
Cache operator overload resolution results on global session, so each new Session doesn't need to repetitively run through overload resolution from scratch.

* SP004: implement initialize list translation to ctor
- We synthesize a member-wise constructor for each struct follow
the rules described in SP004.
- Add logic to translate the initialize list to constructor invoke
- Add cuda-host decoration for the synthesized constructor
- Remove the default constructor when we have a valid member init constructor
- Disable -zero-initialize option, will re-implement it in followup (#6109).
- Fix the overload lookup issue
When creating invoke expression for ctor, we need to call
ResolveInvoke() to find us the best candidates, however
the existing lookup logic could find us the base constructor
for child struct, we should eliminate this case by providing
the LookupOptions::IgnoreInheritance to lookup, this requires
us to create a subcontext on SemanticsVisitor to indicate that
we only want to use this option on looking the constructor.
- Do not implicit initialize a struct that doesn't have explicit default
constructor.
