* Implement warning diagnostic flags for RGBFIX
* `-m/--mbc-type help` prints to stdout
* Support `-m list` as well as `-m help`
* Make invalid `rgbfix -l` characters a fatal error, like other invalid CLI arguments
* Refactor fix/main.cpp into multiple files
* Remove `err` and `warn`, keep `errx` and `warnx`, using them in RGBGFX too
* Separate RGBGFX and RGBLINK warnings/errors from main options
* Separate `report` function into `error` and `fatal` messages
* Implicit newlines for most RGBASM errors
- `-fsanitize=undefined` encompasses multiple checks we were specifying
- "detect_leaks=1" for `__asan_default_options` checks for memory leaks
(except for with macOS clang++, which does not support LSan)
- `-fsanitize=float-divide-by-zero` is an extra UBSan check
(and reveals a UB bug to fix with fixed-point `DIV` and `LOG`)
Fixes `make develop` with Clang 17.
The warning only triggers on the auto-generated `yynerrs_` in `src/asm/parser.cpp`,
so it's not very useful to us right now.
macOS 10.15 introduced full `std::filesystem::path` support.
Before that our use of it would cause the build to fail.
This was not caught because "-mmacosx-version-min=10.9" was only
being passed to clang++ for release builds.
This passes that flag in a new static CI test build, and introduces
a hack developed by @LIJI32 to silence the availability errors,
since we use features already available in macOS 10.9.
This means we are testing both "vanilla" building,
and building static binaries using the same configuration
as during release, which should help avoiding last-minute
surprises.
Ensure consistency in linker script parser interface
Make the declaration and definition visible when compiling
so that the compiler can warn about inconsistencies.

Notable side effects:
* Use the standard-conformant MSVC preproc
* Add test for linker script INCLUDE
* Improve wording of placement conflict errors
* Fix errors from not newline-terminated files
* Teach checkdiff about the linker script doc
* Call linker script "commands" "directives" instead
