[ASTERIXDB-2367][STO] Various Fixes for BufferCache

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Ensure fileInfo is deleted from FileInfoMap when delete a file from
buffer cache
- When delete old components after merge, ensure components are first
purged to avoid sweep old pages
- When open/create/delete files from buffer cache, use file-level
synchronization to reduce blocking. Certain operations such as
createFile/deleteFile can take long time if the disk is busy.
