[ASTERIXDB-2980][*DB][IDX] Add the option "CAST (DEFAULT NULL)" to CREATE INDEX statement

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

Details:
Add the option "CAST (DEFAULT NULL)" to CREATE INDEX statement.

- when CAST (DEFAULT NULL) is specified in CREATE INDEX, use
  constructor types to cast the input type to the indexed field type as
  follows: CONSTRUCTOR(IF_MISSING(indexed_field, NULL)).
- in index bulk load path, cast only the indexed fields instead of the
  whole dataset record.
- allow CAST (DEFAULT NULL) only for b-trees.
- add tests.
