[AMDGPU] Implement "non-av" semantics using metadata

When the MMRA tag !{!"amdgcn-av", !"none"} is present on a synchronization
operation (fence, atomic load/store/rmw/cmpxchg), suppress cache writeback
(MakeAvailable) and cache invalidation (MakeVisible) while preserving
memory ordering (waits).

This implements the metadata proposed in #191246.

Fixes: LCOMPILER-2214

[AMDGPU] Refactor insertRelease into insertWriteback + insertWait (NFC)

A release consists of two actions: write-back the current cache, and wait for
"relevant" outstanding operations to complete. With the new memory model, it is
possible to disable the cache write-back using "av none" semantics. This patch
cleanly separates the existing implementation so that the write-backs can be
selectively applied when such metadata is present.

[AMDGPU] Introduce ABI occupancy for object linking

This PR introduces ABI occupancy as the contract used to compile functions under
object linking. The default is derived from the occupancy needed for a 1024
workitem workgroup, can be overridden with `-amdgpu-abi-waves-per-eu`, and can
be overridden per function by `amdgpu-flat-work-group-size` or tightened by an
accepted `amdgpu-waves-per-eu` hint.

The backend emits the selected occupancy in `.amdgpu.info` and uses it to
enforce the object linking register budget.

[clang] implement CWG2064: ignore value dependence for decltype

The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.

This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.

This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.
