Add regular expression support to streaming search
Introduces an explicit regex query term node (which wraps an
RE2 regex instance internally) and extends the existing
UTF-8 flexible string searcher to use this query node.
Regex matching is optionally case (in)sensitive depending
on the normalization mode used.
Note on `searcher/searcher_test.cpp`: this adds a magic
sentinel `#` char prefix to query term parsing in the test
to let a query term be interpreted as a regex rather than
exact/prefix/suffix/substring match.
