* Added deep freeze functionality
* Adding support for selecting sound chip
* Adding LUA interface to the deepfreeze list

This lets us support mapper32k_w without needing extra hacks. Because of lazystates, this doesn't hurt us on state size either (lazystates did not exists when we did 722358c1b1
Create an all new waterbox build environment:
WSL2 + Ubuntu 20.04 LTS (Other linuxes may work)
Musl libc with waterbox customizations
LLVM's libclang-rt, libunwind, libcxxabi, libcxx
Static linking to elf files
Compared with the old system, this is easier to set up a dev env for and easier to update in the future. The executables are larger but produce smaller savestates due to static linking. The modern toolchain means advanced library features and language features that sometimes appear in some upstream cores will be reusable.
If you tried setting your gains to 100 in the previous patch, it worked sort of, but I decided to incorporate ekeeke/Genesis-Plus-GX@f6f4556 as well to actually fix it completely, and rescale the setting properly so that 1.0 really is neutral gain.
Fixes#1319
gpgx upstream automatically gives 64KiB sram to every game of size 2MB or lower, unless specifically overrided. That sucks and we don't do it. But some games do need it; there's not enough information to autodetect otherwise. So add a flag that we can set in gameDB for it, and set it true for two known games that have problems otherwise.
