📄 Description

This PR enables LTO if the respective build toolchain supports it.

During my tests LTO enabled builds of shadPS4 performed noticeably better in certain games (e.g. Bloodborne).
Especially 1% low FPS measurement results were better and perceived stutter was less.

This observation was backed by other testers that were given a test build by me.
