feat(X / Twitter): Allow choice of link sharing domains

[matthewasage]

Feature description

#3753 added changing the link sharing domain to FxTwitter (fxtwitter.com).

My feature request is to allow for FxTwitter's alternative domain to be selected (fixupx.com) as the link sharing domain, as well as BetterTwitFix (vxtwitter.com/fixvx.com) which is a similar service.

The domain of choice could be selected within the patch options, before patching.

Motivation

Both services (FxTwitter, BetterTwitFix) offer the same service but their implementations differ in a few, noticeable ways (e.g. multi-image tweets preview layout is handled differently between the two, preview text is handled differently, nested tweets are shown differently, etc). These differences are contrasting enough that one user might prefer one link sharing service over the other.
