Separating this out from the QUIC PR to allow it to be separately reviewed. The QUIC implementation makes use of the hdr_histogram for dynamic performance monitoring. This introduces a BaseObject class that allows the internal histograms to be accessed on the JavaScript side and adds a generic Histogram class that will be used by both QUIC and perf_hooks (for the event loop delay monitoring).

Separating this out from the QUIC PR to allow it to be separately reviewed. The QUIC implementation makes use of the hdr_histogram for dynamic performance monitoring. This introduces a BaseObject-derived class that allows the internal histograms to be accessed on the JavaScript side and adds a generic Histogram class that will be used by both QUIC and perf_hooks (for the event loop delay monitoring). There is no QUIC specific stuff in this PR.
