acpica: upgrade 20220331 -> 20230331

License-Update: Copyright year updated to 2023.

Changelog:
==========
-Update all copyright notices to the year 2023. This effects all source
 modules, as well as utility signons.
-Add OS-specific support for Zephyr RTOS.
-Fix miscellaneous code that accesses various objects.
-Remove some dead code.
-Add C ?Flexible Array? support.
-Add support for 64 bit LoongArch compilation.
-Add first batch of RISC-V related definitions.
-Performed a global automated update to remove tabs, fix indentation
 issues, etc.
-Allow disabling of -Werror. For distro maintainers having '-Werror' can
 delay update of GCC. Since every GCC release might add new warnings that
 were not yet captured, it might break the build of packages. With this
 change, distros can now build with 'NOWERROR=TRUE' instead of patching
 either the errors or the makefiles. The default behavior keeps on using
 '-Werror'.
