Subject: [PATCH] CI: add Linux GCC/Clang build (with OpenGL deps + SSE4.1)
 (#59)

* ci: add Linux GCC/Clang workflow

Add a Linux job that builds with GCC and Clang using Ninja and runs tests

* ci: install OpenGL headers on Linux

Fix raylib configure by installing libgl-dev in the Linux GCC/Clang job

* ci: enable SSE4.1 for Linux builds

Pass -msse4.1 to GCC/Clang in the Linux workflow to satisfy runtime intrinsics
