git: Various style fixes everywhere, removing whitespaces (#321)

* repo-wide: trim trailing spaces

Note: This doesn't touch the .tbl files in encodings/ since they include
meaningful trailing spaces (`20= `)

* patterns: clean up duplicate semicolons

* ELF: add header magic check

* glTF: use type::Magic for magic value

* glTF: check that the file size in the header matches

* xgstexture: fix generics syntax for magic value

* JPEG: define hex enum with 0x00 instead of 0X00

* CI: update deprecated actions
