1ebc1895ee A32/x64: Create a global_offset optimization for the page table (#507)
Instead of looking up the page table like:
  table[addr >> 12][addr & 0xFFF]
We can use a global offset on the table to query the memory like:
  table[addr >> 12][addr]

This saves two instructions on *every* memory access within the recompiler.

Original change by degasus in A64 emitter

af3614553b A64/impl: Move AccType and MemOp enum into general IR emitter header
These will be used by both frontends in the future, so this performs the
migratory changes separate from the changes that will make use of them.

Thanks at skmp for the idea.

2f2a859615 a32_jitstate: Consolidate upper bits of location descriptor into upper_location_descriptor
Also solves a performance regression initially introduced by b6e8297e369f2dc4758bafe944e51efb8d1a2552,
primarily due to excessively mismatched load/store sizes causing less than optimal load-to-store forwarding.

acd7ac5ed3 CMakeLists: Handle DYNARMIC_NO_BUNDLED_FMT in relation to export()
This is pretty gross, but until DYNARMIC_NO_BUNDLED_FMT is eliminated,
this fixes the use of it in existing libraries or applications making
use of dynarmic.

6187de7ca7 a32_interface: std::move UserConfig where applicable
UserConfig instances contain up to 16 std::shared_ptr<Coprocessor>
instances. We can std::move here to avoid performing 16 redundant atomic
reference increment and decrement operations.

Mostly inconsequential on x64, but we may as well signify intent.
