Refactor: moved list of games appid to appids.py

[QtRoS]

Automatically parsed and replaced (with regexp, not AI) most of appid literals in proton. Why? Because 3 year old comment says:

#hopefully short-lived, app-specific workarounds for Proton bugs

Seems that it's time to make such lists legit, because makes codebase look a bit more solid :)

BTW, I left old ids in comments like this:

if appid in [
                AppID.AS_DUSK_FALLS, # 1341820
                AppID.CREATIVERSE, # 280790
                AppID.THE_ELDER_SCROLLS_ONLINE, # 306130

only to simplify review process. Once it's done they can be removed IMO.

P.S. Maybe this function worth adding to appids.py:

def name_to_constant(name):
    name = name.upper()
    name = re.sub(r"[\"'\[\]\(\):®]", '', name)
    name = re.sub(r'[ &\-\.,/+]+', '_', name)
    name = re.sub(r'__+', '_', name)
    return name.strip('_')

Later everyone can use it to add new games.
