[cmake, tools] update CPMUtil and add support for CPMUtil bundled Qt, module updates, cleanups (#3289)

Browse source 
Support for bundled Qt, not through aqtinstall but rather my CI. Multimedia is
implemented too, works on both Windows and Linux, though we don't
actually use it so it doesn't really matter. Contains Declarative and all that so the Quick frontend will work once it becomes a thing.

Some options have changed, notably w.r.t LTO and faster
linker, which are now handled directly in the modules.

CPMUtil also has support for custom dirs (`PackageName_CUSTOM_DIR`) now. Probably most useful for adding external fragment shaders and whatnot.

- mold (GCC only) - generally does well on GCC
- lld - preferred on clang
- bfd - the final fallback
- If none are found (macOS uses ld.prime, etc) just use the default linker
- If none are found just use the default linker
