ci/linux: Upload separated debug symbols

Creates a new archive with a debug suffix that contains the debug symbols from
compiling yuzu for mainline. The yuzu executable also gets a GNU debug link to the symbols file.
ci/linux: Compile with debug symbols and upload separately

Currently only uploads for yuzu but yuzu-cmd or other future executables can be
added to the for-loop's parameters.
