* codepage: add single-byte code page support
Add std::encoding::codepage with a shared engine for converting between
single-byte code pages and UTF-8 using table-driven mappings.
Introduce generated tables and wrappers for several code pages[1] each
exposing encode/decode helpers built on a common CodePageTable
structure.
The mapping data is generated by cpgen[2] from the Unicode Consortium’s
published code page mapping files and follows the Unicode standard’s
interpretation of control characters (abstract characters) rather than
historical VGA glyph shapes.
[1] Code page overview/groups:
DOS/OEM code pages (legacy PC):
cp437 cp737 cp775 cp850 cp852 cp855 cp857 cp860 cp861 cp862 cp863
cp864 cp865 cp866 cp869 cp874
Windows code pages (ANSI/Windows):
cp1250 cp1251 cp1252 cp1253 cp1254 cp1255 cp1256 cp1257 cp1258
ISO/IEC 8859 series (Latin/Regional):
iso_8859_1 iso_8859_2 iso_8859_3 iso_8859_4 iso_8859_5 iso_8859_6
iso_8859_7 iso_8859_8 iso_8859_9 iso_8859_10 iso_8859_11 iso_8859_13

- Printing stacktrace uses its own temp allocator.
- `@pool` no longer takes an argument.
- `Allocator` interface removes `mark` and `reset`.
- DynamicArenaAllocator has changed init function.
- Added `BackedArenaAllocator` which is allocated to a fixed size, then allocates on the backing allocator and supports mark/reset.
Ensure that the URL alphabet for base64 is used with the urlencode
functions (urlencode, urlencode_buffer, urlencode_temp and
urlencode_new) are used. Add a new test.
Fix the base64 decoding. If there's an 'A' character in the encoded
text, the base64 decode function returns an INVALID_PADDING error. The
reason lies in the way Base64Decoder.init tries to find a suitable
invalid character. Fix this by defining the invalid character as 0xff
(which is already the case for a decoding without padding).
This error has not been caught by the test harness, because no test
contains an 'A' character in the the encoded text yet. Add a new test.
Upgrade of mingw in CI. Fix problems using reflection on interface types #1203. Improved debug information on defer. $foreach doesn't create an implicit syntactic scope.
Error if `@if` depends on `@if`. Updated Linux stacktrace. Fix of default argument stacktrace. Allow linking libraries directly by file path. Improve inlining warning messages. Added `index_of_char_from`. Compiler crash using enum nameof from different module #1205. Removed unused fields in find_msvc. Use vswhere to find msvc. Update tests for LLVM 19
