Tony Wasserka 60bc5944db CodeCache: Slightly optimize cache file writing 
ftruncate only requires one call (and one extra seek) instead up to 64 manual
zero writes.

Tony Wasserka 86e28c6d34 CodeCache: Move bounds check to FEXOfflineCompiler 
The previous check site would easily fail when loading caches for binaries
with multiple executable sections.

It makes much more sense to refuse generating caches anyway: The condition
effectively checked for invalid code map entries, so FEXOfflineCompiler
should reject them as bad inputs.

crueter 33a01f2773 Core: Use long commit hash instead of abbreviating 
Fixes #5230

Basically just stores it as an array of `uint8_t`, and automatically
pads it out to 24 bytes. Hopefully FEX never reaches SHA1 collisions so
this should (TM) never collide.

Note: I have no idea how fmt will handle that format string with an
array of uint8_t.

Tony Wasserka 31d5805681 CodeCache: Ensure CodeBuffer is large enough for validation run

Ryan Houdek 3d989dbaff FEXCore: Disable 48-bit VA optimization 
This breaks relocations currently due to not handling negatives and also
an interesting overwriting problem.

Not that big of a deal, it's only a minor optimization anyway.

Fixes #5227

Lioncache 0107338020 CodeCache: Fix misparenthesized expression in SaveData() 
Fixes a -Wshift-op-parentheses warning, and what seems to be a
legitimate bug, based off some quick reading.

Ryan Houdek d2b9bfd6ee Arm64Emitter: Changes LoadConstant to support Pad and byte width 
Instead of just a trivial pad being on or off, support a tri-state
on/off/auto where on will always pad, off will never pad, and auto will
pad only if code caching is enabled.

Further augment this by allowing a byte-width to be passed in, which can
be used with pointers to force a 48-bit VA width to only ever pad to
three instructions, reducing the common worst-case situation from 4
instructions to 3. This works because we're not going to expose a VA
width larger than 47-bit to the guest.

Fixes the handful of use-cases that explicitly chose their NOP padding,
and a bug in Arm64Relocations.cpp where it was incorrectly asking to not
receive padding even though it requires it.

Ryan Houdek 6d351ec47f FEXCore/CodeCache: Moves spin-loop in to a WFE loop 
Saves power and responds faster. Pass in the atomic to `WaitPred` with
the predicate checking if the buffer has been flushed yet. Same
behaviour as previous code but more efficient on our hardware.
