ci: Add GCC build job for Linux (shadps4-emu#2027)

* Add GCC CI build job

* gcc-ci: Change Clang CI job naming to avoid confusion

* gcc-ci: Remove GCC CI job from pre-release

This also removes the packaging step for linux-sdl-gcc and linux-qt-gcc so that the only available artifacts for download are compiled with Clang

* gcc-ci: Remove -clang prefix from Clang build jobs

* hot-fix

* specify gcc-14

* hot-fix: use system rapidjson

* use rapidjson-dev

* revert "use system rapidjson"
