BUG: fix boolean array skipna=False for .any() and .all()

I added "not self._mask.any()" to check if there is no missing value for both .any() and .all() when skipna is False. It looks fine for the example you provided.

Thanks for the PR - does this close a particular issue? Can you add tests? @WillAyd I think yes, and I intend to close the issue here [#33253](https://github.com/pandas-dev/pandas/issues/33253). It is my first time in open source so I am not familiar with PR.

I am not familiar with testing, but I can have a try. Any suggestions before I get started Don't worry about Travis that is failing (that's a general issue, there is already another PR trying to fix that) The any/all tests are here:

https://github.com/pandas-dev/pandas/blob/164064d4d4e79c75a7c2068a76deb5685cd87794/pandas/tests/arrays/boolean/test_reduction.py#L15-L39

so you can add to that test some new cases for the all-True and all-False cases from the issue. Thanks @linxiaow !
