dirstate: remove the python-side whitelist of allowed matchers
This whitelist is too permissive because it allows matchers that contain
disallowed ones deep inside, for example through `intersectionmatcher`.
It is also too restrictive because it doesn't pass through
some of the matchers we support, such as `patternmatcher`.
It's also unnecessary because unsupported matchers raise
`FallbackError` and we fall back anyway.
Making this change makes more of the tests use rust code path,
and therefore subtly change behavior. For example, rust status
in largefiles repos seems to have strange behavior.

Correct the conflict without marking the file as resolved
$ echo "ABCD" > A
$ hg commit -m "Merged"
abort: unresolved merge conflicts (see 'hg help resolve')
[20]
Mark the conflict as resolved and commit
$ hg resolve -m A
(no more unresolved files)
$ hg commit -m "Merged"
Test that if a file is removed but not marked resolved, the commit still fails
