Add DbgGetRegDumpEx to bridge API

Public SDK changes:
- Add LASTSTATUS struct
- Add REGDUMP_V2 struct with LASTSTATUS member
- Add DbgGetRegDumpEx(REGDUMP* regdump, size_t size);

Internal changes:
- Change typedef of _dbg_getregdump to add a size parameter
- Make DbgGetRegDump() pass sizeof(REGDUMP) to _dbg_getregdump to preserve existing behaviour. DbgGetRegDumpEx() forwards the size that was passed to it
