We can no longer make the assumption that all non-vanilla clang versions
are Apple's clang or that all other non vanilla clangs will work with
the given arguments. There are times where additional tools might use non vanilla clang
and the presumed arguments here will break compilation on those
platforms.
We might want to consider adding tooling-specific optimazation functions
long term to fetch desired optimizations on a platform basis.
- Reorders existing code to match Godot.
- Adds `NDEBUG` for non-dev builds.
- Adds `-gdwarf-4` for Clang debug symbols.
- Adds strip link flag for GCC/Clang builds without debug symbols.
Now matches Godot `master` target names and supports the same flags with
the following notable exceptions:
- The default target is "template_debug", since it's compatible with
editor builds (and TOOLS_ENABLED is never used internally).
- separate_debug_symbols is still not supported, and will be done in a
separate commit.
