xenia-cpu: VMX128, FPSCR, decoder split, scheduler, decode/block caches

Browse Source 
Split the monolithic interpreter into cohesive modules: dedicated
decoder (decoder.rs) producing 8-byte DecodedInstr; opcode tables
(opcode.rs); explicit traps (trap.rs); FPSCR helpers (fpscr.rs);
overflow/carry helpers (overflow.rs); a 4 KiB-page-versioned decode
cache and basic-block cache (block_cache.rs); and a full VMX/VMX128
implementation (vmx.rs) covering AltiVec + Xenon's 128-bit extensions.

Add the parallel-execution substrate behind --parallel: a 7-party
phaser (phaser.rs) for round-based barrier sync, ReservationTable
(reservation.rs) for guest LL/SC, and the per-HW-thread scheduler
core (scheduler.rs) that owns ThreadRefs, runqueues, and pending IRQs.

Disassembler is now the single source of truth: disasm.rs gains the
full base + extended + VMX128 mnemonic set, with golden JSON fixtures
and a disasm_goldens test suite. Add a criterion-style interpreter
bench. context.rs grows the per-thread state the new modules need
(reservation slot, FPSCR, vector regs).
