This parameter isn't used by any implementation of onDispatchedEvent,
and keeping the parameter makes later refactorings in this bug more difficult.

We only ever use these for passing them into Endpoint construction.
Let's remove them. Removing them also shows that the corresponding
field in Endpoint is essentially read-only, so we can completely avoid
passing in protocol IDs to Endpoint.
We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

Previously we used the base::StatisticsRecorder object for storage by name.
This is keyed by histogram name, which doesn't match our storage reality anymore.
Instead we use a name to refer to a set of histogram instances that record data from different processes, as well as separating session and subsession data.
In this re-write, we instead introduce the following lookup paths (managed in TelemetryHistogram.cpp):
- Main storage:
- (histogramId, processId, sessionOrSubsession) -> Histogram*
- (histogramId, processId) -> KeyedHistogram* (this handles subsessions internally)
- Lookup:
- (histogramName) -> histogramId
- (HistogramID) -> bool (is recording enabled for this histogram?)
This is wrapped with a few lookup functions.
This also allows us to keep HistogramIDs in the JS histogram instances now, instead of pointers to Histogram instances.
That means Histogram instance life-time management is now properly contained inside TelemetryHistogram.cpp.

- A histogram name identifies a set of histogram instances, for which storage and lookup will be handled in TelemetryHistogram.cpp.
So we remove the names from histogram code.
- Various unused macros in the header are removed.
- Remaining traces of StatisticsRecorder are removed from the Histogram class code.
- Some unused methods are dropped that were about printing histograms to ASCII etc.

The Chromium IPC histogram code used the StatisticsRecorder object for storage.
This is keyed by histogram name, which doesn't match our storage reality anymore.
Instead we use a name to refer to a set of histogram instances that record data from different processes, as well as separating session and subsession data.
Consequently we need to rewrite this storage, which means StatisticsRecorder is not used anymore.

Since the default size is 64, we only care about message size which is > 64 bytes.
