develop/ktcc: Post-SVN tidy (#425)

- Move source code from `trunk` into root directory.
- Update build files and ASM include paths. Add SPDX license header where appropriate.
- These changes also update the CI build files in `.gitea/workflows/`.
- Note: Line endings standardised from `CRLF` > `LF`, so best to view diffs with whitespace changes hidden.

(Work towards [#75](KolibriOS/kolibrios#75), point 3)
