Add UsageCounters for misc Intl features

We need to track misc features launched in 2019 to understand the impact.
Also we need to measure the v8BreakIterator usage of 'word' and 'line'
to lobby the need for 'line' in the replacement standard Intl.Segmenter
which an Apple engineer opposed to include.
