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.

ams: build with -std=gnu++23

strat: fix nx_debug build target

ams: globally prefer R_RETURN to return for ams::Result

ams: use R_SUCCEED, R_THROW globally

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

strat: build sysmodules with -Wextra/-Werror

libstrat: fix compilation without pre-compiled header/without lto

libstrat: enable -Wextra, -Werror ...

This caught an embarrassingly large number of bugs.

strat: use sf::NativeHandle for ipc templating

strat: prefer os::NativeHandle to Handle/svc::Handle where sensible

ams: the copyright^H^H^H^H^H^H^Hmplex plane is the algebraic closure of the reals

scs: implement EventHandlerThread for shell

LogManager: implement system module, client api, logging api (#1617) ...

Some notes:

* Unless `atmosphere!enable_log_manager` is true, Nintendo's log manager will be used instead.
  * This prevents paying memory costs for LM when not enabling logging.
  * To facilitate this, Atmosphere's log manager has a different program id from Nintendo's.
  * `atmosphere!enable_htc` implies `atmosphere!enable_log_manager`.
* LogManager logs to tma, and the SD card (if `lm!enable_sd_card_logging` is true, which it is by default).
* Binary logs are saved to `lm!sd_card_log_output_directory`, which is `atmosphere/binlogs` by default.

ams: convert to util::ConstructAt where appropriate

ams: remove TYPED_STORAGE() macro in favor of template
