ams: basic support for compiling with gcc 15

kern/svc: fix query/insecure names

sdmmc: fix wrong mode select for GcAsic(Fpga)Speed

sdmmc: fix missing call to GetSdStatus at non-uhsi mode

ams: address some warnings when building with gcc-12

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

ams: use R_SUCCEED, R_THROW globally

crypto: fix aes-128 dec on arm64/cortex-a57

os/dd: add missing semicolon to new cache logic

kern: update for new hw maintenance semantics

ncm: update client code to better reflect latest sysupdate

fs: utilities for hac2l to print gc headers

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

lib: simplify pragma macros

libs: begin adding capacity for doing crypto on generic os (using externally-preset keys)

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

crypto: fix asm constraints for memory comparison

fs: add Sha256HashGenerator, LZ4 decompressor

sprofile: various correctness fixes.

crypto: implement md5, which now used by sprof

ams: improve offsetof style consistency

sdmmc: use m_ for member variables

exo/vapours: refactor member variables to m_ over this->

ams: replace most remaining operator & with std::addressof

libstrat: enable -Wextra, -Werror ...

This caught an embarrassingly large number of bugs.

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

os: adopt multiwait naming over waitable

stratosphere: use SdkMutex/SdkRecursiveMutex over Mutex

ams-libs: AMS_ASSERT no longer invokes expression

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.
