Henrik RydgårdandClaude Sonnet 5 d000d5366a Wire the generated ExecInstruction dispatcher into the interpreter's hot loop ...

Adds Core/MIPS/InterpreterDispatch.cpp, the checked-in output of
GenerateInterpreterDispatch() (see the previous commit), and hooks it
into RunUntilFast() in MIPSTables.cpp in place of the old
MIPSGetInstruction()-based table walk + indirect call through
instr->interpret. The checked-with-breakpoints/memchecks path
(RunUntilWithChecks) is untouched for now, since it inspects
MIPSInstruction flags directly and correctness there matters most.

Also fixes a real crash in headless.cpp found while testing this:
cmdLineOptions.gpuBackend.value() would throw when unset (e.g. with
--graphics=software), now uses value_or().

Verified with `test.py -g --cpu=interpreter --graphics=software`:
313/314 pass; the one failure (cpu/fpu/fpu) is a pre-existing
interpreter-vs-JIT denormal (flush-to-zero) difference, confirmed to
fail identically with the old table-walking dispatch, so unrelated to
this change.

Adds Tools/update-dispatcher.py to regenerate InterpreterDispatch.cpp
from a built PPSSPPHeadless binary whenever the MIPSTables.cpp tables
change.
