BUG#27294066 INNODB: FAILING ASSERTION: !(TYPE_MODE & 1024)

Problem :
---------
1. We are setting LOCK_REC_NOT_GAP predicate locks also which
is not meaningful. It is a debug issue.

2. Although supremum record locks are always of type GAP we set
X/S record lock type to share the same BITMAP with record locks.
We are setting LOCK_REC_NOT_GAP for supremum in such cases which
is asserted in some places. It is a debug issue.

Solution :
----------
1. Skip predicate locks while releasing GAP locks
2. Remove supremum record BIT to release GAP lock on supremum
3. Add tests to validate the scenario
