refactor: forallAltTelescope to take altNumParams ( #3230 )
...
this way this function does not have to peek at the `altType` to see
when there are no more arguments, which makes it a bit more explicit,
and also a bit more robust should one apply this function to the type of
an alternative with the motive already instantiated.
It seems this uncovered a variable shadow bug, where the counter `i` was
accidentially reset after removing the `i`’th entry in `ys`.

refactor: CasesOnApp.refineThrough can return a lambda, not an open term ( #2974 )
...
which also removes an error condition at the use site.
While I am at it, I rename a parameter in `GuessLex` that I forgot to
rename earlier.
The effect will be user-visible (in obscure corner cases) with #2960 , so
I’ll have the test there.
A few places would benefit from a `lambdaTelescopeBounded` that
garantees the result has the right length (eta-expanding when
necessary). I’ll look into that separately, and left TODOs here.

feat: Add MatcherApp. and CasesOnApp.refineThrough ( #2882 )
...
these are compagnions to `MatcherApp.addArg` and `CasesOnApp.addArg`
when one only has an
expression (which may not be a type) to transform, but not a concret
values.
This is a prerequisite for guessing lexicographic order (#2874 ). Keeping
this on a separate PR because it’s sizable, and has a clear independent
specification.
