Remove the legacy (non-IR) x86-64 and ARM64 JITs

Browse Source 
Their IR-based replacements stay. The JIT core now creates the IR JIT on both, so "JIT using
IR" is the same as "JIT" on every architecture (ARM32 still uses its legacy JIT for both). The
settings no longer offer it, a saved JIT_IR loads as JIT, and the JIT harness and CPUEquivalence
fuzzer drop the duplicate run.
