fix: nontermination while generating equation lemmas for match-expressions ( #6180 )
...
This PR fixes a non-termination bug that occurred when generating the
match-expression equation theorems. The bug was triggered when the proof
automation for the equation theorem repeatedly applied `injection(` to
the same local declaration, as it could not be removed due to forward
dependencies. See issue #6067 for an example that reproduces this issue.

fix: backtrack at injection failure ( #6109 )
...
This PR fixes an issue in the `injection` tactic. This tactic may
execute multiple sub-tactics. If any of them fail, we must backtrack the
partial assignment. This issue was causing the error: "`mvarId` is
already assigned" in issue #6066 . The issue is not yet resolved, as the
equation generator for the match expressions is failing in the example
provided in this issue.

@Kha I think this one is a good change, there is no real reason for

feat: add introNP and intro1P
...
Versions of `introN` and `intro1` that preserve the binder name.
They are used to implement the idiom: "revert", do something, re-"intro"-tuce
Before this commit `introNP mvarId n` was `intro1 mvarId n [] false`.
