fix: Extract function from trait impl
This change fixes#10036, "Extract to function assist implements nonexistent
trait methods".
When we detect that the extraction is coming from within a trait impl, and that
a `self` param will be necessary, we adjust which `SyntaxNode` to `insert_after`,
and create a new empty `impl` block for the newly extracted function.
publish workflow: Fix names for existing crates
Attempting to publish for example ra_ap_text-edit when ra_ap_text_edit
has already been published is rejected by crates.io.

fix: Extract Function produces duplicate fn names
This change fixes#10037, in more or less the most naive fashion
possible.
We continue to start with the hardcoded default of "fun_name", and now append a
counter to the end of it if that name is already in scope.
In the future, we can probably apply more heuristics here to wind up with more
useful names by default, but for now this resolves the immediate problem.

fix regressions on assignment expressions
This is a follow-up PR on #12428. I'm not sure if this is everything I overlooked, so if there are more things that are not right, we may want to revert #12428.
This should also fix the increase of the type mismatches and the unknown types in diesel in the [metrics](https://rust-analyzer.github.io/metrics/?start=2022-06-23&end=2022-07-01) introduced by #12428.
The regressions are:
- some coercions don't work in the ordinary (i.e. non-destructuring) assignments
In order for coercions on ADT fields instantiations to work, lhs type has to be known before inferring rhs. #12428 changed the inference order, making rhs inferred before lhs, breaking the coercion, so I restored the original inference mechanism for the ordinary assignments.
Note that this kind of coercion doesn't happen in destructuring assigments, because when they are desugared, the struct expression is first assigned to a temporary, which is then assigned to the assignee, which is not coercion site anymore.
- type mismatches on individual identifiers are not reported
