Convert context dependent TrackSelectionParameters to boolean

This avoids that these settings have to be resolved inline,
potentially blocking the main thread. They can be resolved at
the time of track selection on a background thread instead.

As a side effect, we can also remove the context parameter from
the Builder. Having the Context in the Builder is also a bad sign
in the first place because it implies the potentially blocking
calls can happen.
