Matthew Stanley 6ce012df3e fix: wire cdrom_tick into vblank interval, fire IRQ on command completion ...

Two CDROM issues preventing BIOS from progressing past Sony logo:

1. cdrom_tick() was never called — delayed CDROM responses (GetStatus,
   Init, Pause) never completed because pending.delay was never
   decremented. Wired into psx_check_interrupts vblank interval.

2. exec_command() called set_irq() but not fire_cdrom_irq() for
   immediate responses (GetStat, SetLoc, Demute, etc.). The CDROM
   IRQ flag was set internally but i_stat bit 2 was never raised,
   so the BIOS exception handler never delivered CDROM events.

BIOS still stalls at same draw count — next bug in chain is EvCB
event delivery (TestEvent returns 0 because VBlank events aren't
being written to the event control block table).
