[discover-scanner] allow filtering based on a user given bloom filter indexes (#5075)

Browse Source 
This commit enhances the filtering behavior of Discover Scan. When
filtering is enabled, MLE Discovery Responses with steering data
(bloom filter) not containing a set of bloom filter indexes are
filtered. This commit updates the `DiscoverScanner::Discover()` to
allow filter indexes used for filtering to be optionally specified by
the caller. It can be set to NULL (for default behavior) where the
hash of factory-assigned EUI64 of the device would be used to derive
the bloom filter indexes
