QT Frontend: Add disk shader loading progress bar

Browse source 
Until we get a on screen display or async shader loading, we should at
least have some measure of progress in the meantime. This is 90% a port
from the loading screen I made for yuzu, but with a slightly different
changed detection for when to display the ETA. Now we keep track of a
rolling estimate for shader load ETA and only display a ETA if its going
to take longer than 10 seconds.
