[ASTERIXDB-2270][STO] Fix Deadlock in LSMRTree
- user model changes: no
- storage format changes: no
- interface changes: no
details:
- The LSMRTreeWithAntiMatterTuplesSearchCursor was
using the includeMutableComponent incorrectly to
determine whether memory components are included.
- This change ensures that memory components cursors
are always closed and destroyed as part of the
cursor lifecycle.
- The change also includes a check that fails if a
virtual file was deleted and some of its pages
are still latched.
Validate pages of deleted vbc files are not latched
