Common::unordered_map/set defaulted to std::hash, a byte-wise FNV-1a on MSVC for
integers and pointers, which boost's flat containers then mix again: the GPU thread's
page maps (shader and query cache invalidation, per inline upload) spent ~1% in it.
Integer and pointer keys now go through as they are and boost mixes them.
BufferCache::IsRegionGpuModified visited every GPU-written range inside the query just
to answer yes or no; without per-fence downloads those ranges stay fragmented and it was
~4% of title 1's GPU thread (inline uploads). RangeSet::Intersects answers with one
lookup. Inline uploads: 10.5% -> 7.5% of the GPU thread.

Replaces all instances of ankerl's unordered map/set with boost's
`unordered_flat_*` classes. This uses std::hash since boost::hash is
actually a lot slower.
Also adds an abstraction layer in `Common` so future changes are quicker
and easier.
Other implementation details:
- ankerl provided hash specializations for tuple and pair, so those were
ported here
- std::erase_if doesn't work on boost, so just used the ADL'd erase_if
This should be about equal or superior performance as unordered_dense for everything except iteration.

Ports a small subset of boost's hash_value implementation (<= 1.80.0).
