radio-group, checkbox-group, select: Specify value via  field in BEMJSO...

...N #1055
@dfilatov I tried to add [some silly benchmarks][1] with 10 huge selects (100+ items per each) on a single page, but haven't noticed any significant difference in bh rendering between `v2` version on select, this one and with functions moved outside the `match`'es.
