mrambacher 9a116ab4b4 Add NewMetaDataIterator method (#8692) 
Summary:
Fixes a problem where the iterator for metadata was being treated as a non-user key when in fact it was a user key.  This led to a problem where the property keys could not be searched for correctly.

The main exposure of this problem was that the HashIndexReader could not get the "prefixes" property correctly, resulting in the failure of retrieval/creation of the BlockPrefixIndex.

Added BlockBasedTableTest.SeekMetaBlocks test to validate this condition.

Fixing this condition exposed two other tests (SeekWithPrefixLongerThanKey, MultiGetPrefixFilter) that passed incorrectly previously and now failed.  Updated those two tests to pass.  Not sure if the tests are functionally correct/still appropriate, but made them pass...
