ams: mark ams::Result [[nodiscard]] (partially complete). ...

NOTE: This work is not yet fully complete; kernel is done, but
it was taking an exceedingly long time to get through libstratosphere.
Thus, I've temporarily added -Wno-error=unused-result for libstratosphere/stratosphere.

All warnings should be fixed to do the same thing Nintendo does as relevant, but this
is taking a phenomenally long time and is not actually the most important work to do,
so it can be put off for some time to prioritize other tasks for 21.0.0 support.

erpt: begin SubmitFsinfo (SubmitMmcDetailInfo)

windows: add brave new mingw compat hook for gcc 12.2.0+

strat: fix linux clang build

strat: fix clang build

windows: link libgcc/libstdc++ statically

symbols: use same strategy on windows as on macOS

use cxxabi for demangling on linux/windows

abort/error: print backtrace, abuse templates, overhaul result/diag (macos not done yet)

libs: add ongoing work to facilitate hactool rewrite

ams: support building unit test programs on windows/linux/macos

strat: use ams::Main() instead of main(argc, argv)

strat: build sysmodules with -Wextra/-Werror

sm: update to excise unnecessary library code

stratosphere: discard unnecessary .eh_frame segment

mem: implement most of StandardAllocator (#860) ...

This was tested using `https://github.com/node-dot-cpp/alloc-test` plus a few other by-hand tests.

It seems to work for the case we care about (sysmodules without thread cache-ing).

External users are advised to build with assertions on and contact SciresM if you find issues.

This is a lot of code to have gotten right in one go, and it was written mostly after midnight while sick, so there are probably un-noticed issues.

stratosphere template: allow for per-module defines

buildsystem: more fixes
