Remove everything relating to QT5 in common

This is causing some pretty annoying errors when trying to compile and link common libraries with firmware libraries and since there is no way firmware needs to use QT, there is no need for it in common.

Ugh I guess a bunch of stuff uses types from QT. Most of it doesn't seem to be used by firmware but there are a few instances where firmware relies on files in common which use QT types. This should be changed if at all possible
