OpenGL: Remove "-legacy" flag

Browse Source 
"Intel legacy mode" was a special mode to workaround various Intel OpenGL driver limitations during the earlier years of Cemu. It's been unmaintained for years and no longer serves a purpose.

If we ever bring back compatibility with ancient Intel GPUs it should be done in a more structured way than a blunt yes/no flag.
