Add LR triggers as axes, half press to initiate a press, add GC axis id in config, clarify some code blocks for better readability

This fixes some cases where entries could have been removed multiple
times reading freed memory. To address this issue this commit removes
duplicates from entries marked for removal and sorts out the removal
process to fix another use-after-free situation.

Another issue fixed in this commit is orphan invalidation cache entries.
Previously only the entries that were invalidated in the current
operations had its entries removed. This led to more use-after-free
situations when these entries were actually invalidated but referenced
an object that didn't exist.

Supersedes #4068 see for details.

Our codebase uppercases member function names.

Prevents the singleton from being moved from.

operator= typically returns a reference, it's not void.

While we're at it, we can correct the parameter formatting to adhere to the
codebase.

Like MirrorOnceBorder, this requires the GL_EXT_texture_mirror_clamp extension. This extension is unfortunately not available on Intel's drivers (both Windows proprietary and Linux Mesa). Use GL_MIRROR_CLAMP_TO_EDGE as a fallback if the extension is unavailable.

Macro code is just uploaded sequentially from a starting address, however that does not mean the entry point for the macro is at that address. This PR adds preliminary support for executing macros in the middle of our cached code.

On gcc/ld, and clang/lld, fmt::v6 symbols are excluded, so linking
fails. This fixes the issue.

Note: This was included in the FindBoost changes I shared with
BlinkHawk, however only they were merged. I'm not sure if it was missed,
or if there was an issue with this part of the change.
