Simplify GrDiffProcessor

The diff processor's job is quite simple: It converts the diff as
produced by the backend (along with some prefs) to a list of
GrDiffGroups.

It is mindful about not blocking the JS execution by doing this is
smaller blocks. This is mostly useful, because emitted groups are
picked up immediately for rendering. Processing the diff itself is
very fast: 100,000 lines can be processed in 100 ms.

Ultimately we want to move this conversion process into the new
diff model. And gr-diff should eventually become a Lit component
that just listens to groups from the model.

In a first step we are removing a bunch of undesired complexity from
the processor: Let's not try to re-use the diff processor twice and
let's make the cancelling() actually work while making it much simpler
at the same time.

Move all initializations of processor properties into the same spot.
