change default pref for viewport fitting (#50749)

About The Pull Request

Changes the pref for fitting viewport to automatic. This not being the default has always confused me, and should resolve some teething issues widescreen is having.
Changelog

cl
tweak: Auto fit viewport is now the default, and everyone's setting for this has been reset to the default. If you don't know what this means, it's safe to ignore.
