Lazy-ify ValueMatcher BitSet optimization for string dimensions. (#5403)
* Lazy-ify ValueMatcher BitSet optimization for string dimensions.

The idea is that if the prior evaluated filters are decently selective,
such that they mean we won't see all possible values of the later
filters, then the eager version of the optimization is too wasteful.

This involves checking an extra bitset, but the overhead is small even
if the lazy-ification is useless.

* Remove import.

* Minor transformation
