Restructure dependencies and update to C++20

- Nuked static_assert from almost everywhere in the project
- Nuked binary dependency support. Might add one later though
- Separated dependency headers into a separate include subdirectory
- Grafted a thirdpartylegalnotices.txt generator from RITEG
- Pushed development snapshot version to 2126 (26th week of 2025)
