Improve doc/state-contents.txt

Part of a fix for #40136.

This patch adds all the state file entries to the documentation, and
documents the ones that I understand well.

MinutesSinceUserActivity (integer)
Dormant (0, 1, or "auto")
These values are used to keep track of how long Tor has been idle,
for the purpose of becoming 'dormant' after a long period without
any user-initiated requests.
"MinutesSinceUserActivity" is the number of minutes since the last
time the user asked us to do something. It is set to zero if we're
dormant.
"Dormant" is 1 if Tor was dormant when it wrote its state file, 0 if
Tor was active, and "auto" if Tor was starting for the first time.

The format is "transportname addr:port", to remember the address

this information to spawn pluggable transport listeners in the
same IP address and TCP port even after tor client restarts.
BWHistory___Ends (ISO time)
BWHistory___Interval (integer, number of seconds)
BWHistory___Values (comma-separated list of integer)
BWHistory___Maxima (comma-separated list of integer)
These values record bandwidth history. The "Values" fields are a list,
for some number of "Intervals", of the total amount read/written during
that integer. The "Maxima" are the highest burst for each interval.
Interval duration is set by the "Interval" field, in seconds. The
"Ends" field is the ending time of the last interval in each list.
Recognized values for "___" are:
Read -- total bytes read
Write -- total bytes written
DirRead -- total bytes read for directory connections.
DirWrite -- total bytes written for directory connections.
IPv6Read -- total bytes read on IPv6 connections
IPv6Write -- total bytes written on IPv6 connections

Guard [key=value] [key=value]...
Describes a single entry guard used by the client. Key=value
entries with unrecognized keys are persisted. Order is not
significant. For more information about terminology used here,
system, see guard-spec.txt in the tor specifications repository.
Recognized keys are:
in (string)
The name of a guard selection that this guard is in.
rsa_id (string)
RSA fingerprint of this guard, without spaces.
nickname (string)
Declared nickname of this guard.
sampled_on (Time in ISO YYYY-MM-DDTHH:MM:SS format)
When was this guard added to the Guard sample?
sampled_by (tor version)
Which version of Tor added this Guard to the sample?
(Used to help with debugging.)
sampled_idx (integer)
Index of this guard among sampled guards.
listed (boolean)
Did this guard appear in the most recent consensus?
unlisted_since (Time in ISO YYYY-MM-DDTHH:MM:SS format)
If this guard is not listed, when is the earliest
consensus in which we found it unlisted?
confirmed_on (Time in ISO YYYY-MM-DDTHH:MM:SS format)
When did this guard become confirmed?
confirmed_idx (integer)
Index of this guard among confirmed guards.

It was once used to ensure that v3 onion service directory revision
numbers were strictly increasing; we now use an order-preserving
encryption scheme for that purpose.
These values record bandwidth history. The "Values" fields are a list, for
some number of "Intervals", of the total amount read/written during that
integer. The "Maxima" are the highest burst for each interval.
Interval duration is set by the "Interval" field, in seconds. The
"Ends" field is the ending time of the last interval in each list.
The *Read* and *Write* fields are the total amount read and
written; the *DirRead* and *DirWrite* variants are for directory
traffic only.
