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.

  $ echo 'syntax:re' >> .hgignore

  $ echo '^d1$' >> .hgignore

    24

  $ hg commit -Am "ignore d1"

    25

  adding .hgignore

Now d1 is a directory that's both committed and ignored.

    28

Untracked files in d2 are still shown, but ones in d1 are ignored:

  $ touch d2/g

  $ RAYON_NUM_THREADS=1 hg status
