g65816: Emulation accuracy fixes - (stack,S),Y and emulation mode quirks (#12079)
* Fix wraparound in (stack,S),Y addressing mode * Emulate (direct,X) emulation mode wraparound bug, fix handling of direct page accesses in emulation mode. * Ignore emulation mode for 24-bit pointer reads/writes * Force usage of native 16-bit stack handling for 65816-exclusive stack instructions * PEI also forces native 16-bit direct page handling * PLB reads from ($200) instead of ($100) when S=$1FF in emulation mode
