src,test: ensure that V8 fast APIs are called
Adds a debug-only macro that can be used to track when a V8 fast API is
called. A map of counters is maintained in in thread-local storage and
an internal API can be called to get the total count associated with
a call id.
Specific tests are added and `crypto.timingSafeEqual` as well as
internal documentation are updated to show how to use the macro
and test fast API calls without running long loops.
