* Add ISO 8601 date format to notification output
This is actually supposed to be the only output date format used,
per https://www.mediawiki.org/wiki/API:Data_formats#Timestamps , but
I'm not doing anything to deprecate the others right now.
* Change wgEchoSeenTime to use ISO 8601. mwgrep and extension grep do
not show any usages. However, since it is a breaking change, to
minimize disruption, I'm also using this opportunity to change
'message' to 'notice'.
* Remove wgEchoInitialNotifCount. I was going to also change 'message'
to 'notice' here too, but then I saw it was totally unused.
(It was read in Echo to populate a JS variable, but then it was
unused.)
* Make sure the Special:Notifications page aggregation by days is
done by local days, even though the timestamp per item is still
UTC. This is to make sure the days are displayed correctly in
the local timezone.
* Change all reverse sorting callbacks to handle comparisons of
ISO 8601.

Despite claiming to be about categories, $wgEchoDefaultNotificationTypes
was actually configuring both categories and types (which go inside
categories).
For example, 'thank-you-edit' is a type, but 'emailuser' is both
a category and a type (when used as a category, this has special
effects at Special:Preferences).
Since types and categories can and sometimes do have the same names,
this leaves no way to properly and clearly configure them. It also
makes it difficult to document what is going on (as required by
T132127).
Split into three variables:
$wgDefaultNotifyTypeAvailability - Applies unless overriden
$wgNotifyTypeAvailabilityByCategory - By category; this can be and is
displayed at Special:Preferences
$wgNotifyTypeAvailabilityByNotificationType - By type; this cannot
be displayed at Special:Preferences. To avoid confusing the user,
we introduce a restriction (which was previously followed in practice,
AFAICT) that types can only be overridden if the category is not
displayed in preferences.
Otherwise, it can look to the user like a category is on/off, but the
types within might have the opposite state.
Due to this configuration change, this is a breaking change, and needs
coordinated deployments.
This also lays the groundwork for T132127
Also change terminology to consistently use "notify type" for web/email.
It was mixing between that and output format (which unfortunately
sounds like the API format, e.g. 'model').
