FeatureInfo: Remove allowed_extensions and init workarounds early

FeatureInfo: Remove allowed_extensions and init workarounds early

This removes passing allowed_extensions all the way through, since it
was ignored anyways. It also initializes the workarounds from the
commandline during FeatureInfo construction so it can be used to
make decisions before the first context is created and initialized.

I'd like to make virtual contexts a proper workaround flag on Android, and for
that the cmdline needs to be parsed before the first context is created.
(Android has too much hardcoded tweaks and workarounds in too many places.)

Btw, this is where |allowed_extensions| went to being ignored in FeatureInfo:

Not sure if we ever passed in anything but NULL/"*" anyways.
