[dynarmic] Coalesce non-exclusive Write/Read fallback functions (#4158)

Browse Source 
the general idea is to have a common procedure form whom to call
this way theres less "jumping around" for values of different sizes
additionally this **should** allow for better codegen since
most of the u8,u16,u32,u64 can be held within a u64
theoretically this means that you could deifne callbacks in suck
a way that it's essentially as costly as a `mov r64, m64`
but that's not doable due to the fact we have to do translations...

Is this a good change?
Primarily aimed for x86 and ARM to benefit, but I suppose LooooooongArch64 can benefit too.
