IOS: checkpoint Starlet JIT, PPC cache and Wii timing fixes

Save the remaining ARM JIT and MMU/cache optimizations, accurate Starlet timer and Wiimote report cadence, opt-in PPC event tracing, and full texture hashing in the LLE launcher. Include regression coverage and exclude local profiling artifacts.

Validation: 127 targeted tests from 15 suites passed, with one disabled test. Includes the current user-tested source state following the persistent NAND milestone.
