backend/{a32,a64}_emit_x64: Add config entry to mask page table pointers
...
Add config entry to mask out the lower bits in page table pointers.
This is intended to allow users of Dynarmic to pack small integers
inside pointers and update the pair atomically without locks.
These lower bits can be masked out due to the expected alignment in
pointers inside the page table.
For the given usage, using AND on the pointer acts the same way as a
TEST instruction. That said when the mask value is zero, TEST is still
emitted to keep the same behavior.

emit_x64_vector: GNFI implementation of ArithmeticShiftRightByte
...
The bit-matrix is generated up-front and added to the constant-pool.
I'm using an embedded 64-bit broadcast here(m64bcst) which is the particular
EVEX encoded version of the instruction with AVX512VL+GNFI.
If it ever really matters, then we would ideally detect specific host
features like bare-GFNI and specific subsets of AVX512 and emit
the assembly based on that rather than by the entire Icelake uarch.
