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: initial support (incomplete) for 20.0.0

strat: ldr::PlatformId -> ncm::ContentMetaPlatform

erpt: actually support non-sequential ids, nintendo why

erpt: add remaining SubmitFsInfo helpers

erpt: SubmitFileSystemProxyErrorInfo

erpt: GetMmcErrorInfo, GetSdCard*Info

erpt: begin SubmitFsinfo (SubmitMmcDetailInfo)

erpt: remove deprecated fields, they didn't actually change IDs, just the mapping between id and name table index

erpt: Add basic (TODO-impl post-prerelease) support for 17.0.0 changes

erpt: update server code for 16.0.0 logic changes

erpt: fix multiple issues with automatic report cleanup (thanks @yellows8) ...

* Setting retrieval was performed before the call that used the setting.
* Call to detect number of files passed incomplete path and was guaranteed to fail.
* Call to delete reports passed incomplete path and was guaranteed to do nothing.

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

erpt: add automatic report cleanup mechanism on boot (closes #1795)

ams: deduplicate static initialization logic

sf: prevent emitting mitm/defer code unless server in process supports it

strat: use m_ for member variables

erpt: save 8KB

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

libstrat: enable -Wextra, -Werror ...

This caught an embarrassingly large number of bugs.

strat: use sf::NativeHandle for ipc templating

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

os: adopt multiwait naming over waitable

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-1.0.0: meso no longer optional, remove conditional logic

ams: std::optional -> util::optional

erpt: fix 0x100 byte memory leak on creation of new report

libstrat: fix override operator new to be noexcept (closes #1494)
