Reduces the page entries from 32 bytes to 8 and rewrites `VirtualBuffer` to be more efficient in memory usage and specifically for large zero regions.
The page table will now only reserve 1GiB instead of 4GiB and of this memory it should only use at most ~8MiB.
This PR has the side effect of using Eden on Windows on low memory systems much more plausible since it would previously require ~10GiB of committable memory at front (despite using ~5-6 at most, inadvertently stalling other processes) where as now it should only require around the amount that it'll actually use.

Storage buffers can span GPU pages that aren't contiguous in host memory, but the buffer cache assumed one contiguous buffer per binding, so anything crossing a mapping boundary read the wrong bytes. Multi-range binding resolves the real segments and presents them to the shader as one buffer, aliasing their memory into a sparse VkBuffer or gathering them into a copy, all of this was mostly fixed by making a path to use sparse on buffers (the same way as texture cache has it) and retrieve properly the mapping ranges to the virtual pages, including the actual structure on the use of binding sparse.
Meanwhile this fixes Monster Hunter Sunbreak z-fighting, bad performance and mostly vertex explosions (coming from the contiguous buffer read from the shader's game) it's only the basis for a further investigation towards how are we gonna treat phi calculations, optimized them and mostly eradicate the currently excess of exposure on the textures where the lightning trace should not being reflected.

Problem: In cyrilic idioms, Absolum won't past beyond 1st area (intro miniboss).
From the user panic i`ve extracted these strings:
> GlobalState.request_next()
> save_state_to_saveGame(...)
> platform.ProcessSave()
> bin_serialize_to_file(...)
> StandaloneTypeModel.Write(SaveGame, ...)
> Write(SaveGame.AdventureSaveSlot, ...)
> Write(PlayerState, ...)
> ProtoBuf.ProtoWriter.WriteString(...) + 0xcc
> ProtoBuf.Helpers.DebugAssert(...)
> Debug.Fail(...)
By debugging ProtoBuf.ProtoWriter.WriteString(...) argument it was found that the string Отлично! (Great! expression for combos between 6 and 30 iirc) was reaching a size comparison of different values and causing an assert in guest side..
It seems the game tries to save highest combo level. I've managed to skip this bug by doing a perfect combo for entire level, so that the problematic word never was generated or attempted to be saved.
After further research, the issue chain was identified: Game maths literal string size via two ways and compare, and one of them was getting replaced by a wrong value due to Eden letting the literal string be interpreted as a real instruction.
Logic added:
const bool pair = decltype(l)::ExtractValue(raw) & 1;
const bool fixed_rt2 = decltype(rt2)::ExtractValue(raw) == 0b11111;
return pair || fixed_rt2;
- pair checks bit 21 (L & 1): register-pair instructions actually use Rt2, so they remain accepted.
- For single-register forms, require Rt2 == 31. The table word fails this check, so NCE leaves it intact.

Altough the solution is a case specific guard, it is data agnostic: This is a true fix to avoid a specific case in which a literal may be interpreted as a valid instruction, without interfering with other true instruction cases.

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.

This PR prevents the recompilation of shaders when a new session has been started, based on data found on the recompiler, each new session does still recompile already cached shader cache, reducing the reaction and speed of games by at certain level, this prevent the warm-up with post sessions, only needed the initial warm-up and works globally for all games.

this PR reworks IPS parser to be less stupid
what do i mean by this? well generally give it a bit of
love so it doesn't do a lot of unsound allocations
also simplify the logic greatly (and use memcmp() string idiom
instead of trusting the compiler so blindly...)
no this doesn't mean to uber optimize IPS to handle 999 gb/s
it's more so it doesn't outright crash with edge cases
as the previous codebase was quite spaghetty
also the major overhead is obviously the vector shenanigans
and the I/O -- but thats out of scope
Test that IPSwitch mods still properly work WITH ANY GAME
IF THERE IS ANY REGRESSION IN SOME GAME/MOD THEN
TELL ME
