Add compile-time option which, if enabled, will replace accesses to
psxMemRLUT and psxMemWLUT with a small inline function psxm().

The reasons behind this change are:

- These were some BIG LUTs. On 32-bit, they would account for 512 KiB of
  RAM. On 64-bit, they would account for 1 MiB of RAM. This sounds tiny
  by today's standards, but it still is huge for some of the platforms
  that PCSX supports.

- Computing the pointer isn't that resource-intensive. Still slower than
  reading from a LUT (as long as the LUT entry is in the cache, which it
  should be, as the few valid entries are grouped together), but I doubt
  that it slows down the interpreter by a lot.

- Even if it does slow down the interpreter a bit, it shouldn't be a
  huge deal, given that the interpreter isn't really used nowadays as
  the JITs support all the major CPU architectures, and the interpreter
  is used mostly for debugging purposes. Besides, the two JITs do not
