We're changing the definition of each of the use counter histograms.
Therefore, they need new names, so as to not throw wrenches into the
server-side machinery. This renaming is the most straightforward way to
do things and similar to how we have renamed other histograms before.

This patch teaches gen-histogram-enum.py how to correctly deal with the
situation where there are no use counters. It also adds
mozilla::Telemetry::GetHistogramName for debugging purposes.
We would like to be able to forward-declare Telemetry::ID, so fewer
header files need to include Telemetry.h. Empirical evidence shows that
forward-declaring enums requires either enum classes, or plain
fixed-width enums. Let's opt for the latter here; there's no need to
constrain the size to 16 bits, since Telemetry::IDs are rarely stored in
data structures.
