[CI] Switch to Cachyos-v3 & Fix ccache (Locietta#77)

* ci: switch base container to cachyos-v3 image The cachyos-v3 packages is baselined on x86-64-v3 and built with LTO+O3, which makes it faster than archlinux Also install mimalloc and enable THP to speed up thinlto Somehow Kernel LTO only utilizes one thread most of the time, even if it's thinlto, so the expected gain is small, but still better than nothing * ci: fix ccache ccache has been broken for a while, fortunately relaxed preprocessor checks can fix it The new action also removes stale caches --------- Co-authored-by: Andarwinux <[email protected]>
