kudhru 8aeed08d04 [SPARK-35757][CORE] Add bitwise AND operation and functionality for intersecting bloom filters
### What changes were proposed in this pull request?
This change is for [SPARK-35757](https://issues.apache.org/jira/browse/SPARK-35757) and does the following:

1. adds bitwise AND operation to BitArray (similar to existing `putAll` method)
2. adds an intersect operation for combining bloom filters using bitwise AND operation (similar to existing `mergeInPlace` method).

### Why are the changes needed?
The current bloom filter library only allows combining two bloom filters using OR operation. It is useful to have AND operation as well.

### Does this PR introduce _any_ user-facing change?
No, just adds new methods.

### How was this patch tested?
Just the existing tests.

Closes #32907 from kudhru/master.
