Shokunin 1e6e43639a Title timing constant: [timing] guest_cycle_scale (and _gated) ...

No CPU is emulated: recompiled code charges the guest clock a fixed cost
per instruction. guest_cycle_scale = N charges 1/N of it (instruction,
load, mul/div, GTE latencies, overlay DLL batches) while VBlank, timers,
CD, SPU and DMA keep hardware time, so the game never runs out of frame
time. A title constant in game.toml (1 = faithful, 1..64), never a player
setting; guest_cycle_scale_gated applies it only while the title's mod
opens the gate (psx_guest_cycle_scale_gate_open). PSX_GUEST_CYCLE_SCALE
overrides for testing. A scale other than 1 is folded into the netplay
content fingerprint as a safety net.
