Refactor Percentiles/Ranks aggregation builders and factories (#51887)

- Consolidates HDR/TDigest factories into a single factory
- Consolidates most HDR/TDigest builder into an abstract builder
- Deprecates method(), compression(), numSigFig() in favor of a new
unified PercentileConfig object
- Disallows setting algo options that don't apply to current algo

The unified config method carries both the method and algo-specific
setting. This provides a mechanism to reject settings that apply
to the wrong algorithm.  For BWC the old methods are retained
but marked as deprecated, and can be removed in future versions.
