Refactor disabling the stats logger
Have Snowflake proxy periodically collect throughput stats even if the
stats logger is disabled so that it can be handled by the prometheus
metrics.

Proxy stats log only what occurred that time interval
Modify the periodic stats output by standalone snowflake proxies to only
include the data transferred during the time interval being logged. This
is an improvement of previous behaviour that logged the total data
transferred by all proxy connections that were closed within the time
interval being logged..

Closes #40302:

Move creation of periodic stats task inside proxy library
This adds a new type of SnowflakeEvent. EventOnProxyStats is triggered
by the periodic task run at SummaryInterval and produces an event with a
proxy stats output string.

Zero bytesSyncLogger stats after reading them
This also makes the call to GetStat() more thread safe.

Remove ThroughputSummary from bytesLogger
This was leftover from when we used to log the total throughput of
connections when they close. It should be removed for privacy reasons as
mentioned in

fix(proxy): remove _potential_ deadlock
The `dc.Send()` should increase the `bufferedAmount` value,
so there is no need to add the message length a second time.

Also replace GT with GE, for the case where
`BufferedAmountLowThreshold === maxBufferedAmount`

Currently the deadlock cannot happen because `maxBufferedAmount`
and `BufferedAmountLowThreshold` are too far apart, in fact
the former is 2x the latter.

9ce1de4eee Use Pion's Setting Engine to reduce Multicast DNS noise
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40123

The purpose of the patch is to prevent Pion from opening the mDNS port,
thus preventing snowflake from directly leaking .local candidates.

What this doesn't prevent is the resolution of .local candidates
once they are passed on to the system DNS.
