Fix bios freeze with lightrec, AssertIRQ must change lightrec's CAUSE too

cleanup unused cop0 functions

Codebuffer is much faster due to lightrec's 32-bit LUT optimization

Moved lightning.h to lightning-actual.h and made lightning.h include lightning-actual.h and define HAVE_MMAP for lightning, instead of defining in the Makefile which applied it to other parts of beetle, causing issues on Windows in libretro-common/vfs

…uilds

This allows less code to be emitted by lightrec, but will only
be used if root user enables it with sysctl -w vm.mmap_min_addr=0

…htrec api

This was only useful for debugging, users don't benefit from it, the config
will fallback to using the beetle interpreter if it was selected

The lightrec execute_one function this option called was removed, for
equivalent debugging pass current timestamp instead of next_event_ts to
lightrec_execute

Use lightrec cop2_notify for PGXP, update interpreter to new api

tweak lightrec startup and syncing stuff
remove next_interpreter hack
tweak setoptions, should be safer

Disabled by default for max compatibility
Enabling should generate faster code for most normal games that
do not have sp and gp registers pointing outside of RAM

This was broken by cpu.cpp and cpu_lightrec.cpp being split apart

Add breakpoint handling to match interpreter
Fix setting of options to lightrec

Replaces supported_io_bases array with min/inc/max_io_base
Makes it easier to avoid ranges of address for different platforms
Fix unmap of lightrec codebuffer
