Making project work with clangd:

- Moved a lot of items into separate header files
- Still compiling everything as a single translation unit (but maybe a
  heavier translation unit [if that is possible])
- setup compile_flags, a way to use clangd without using a build system
- stuff like clangd and cmake don't work well with unity builds, so I
  avoid jumping through hoops
