In our autoplay shield-study, we want to collect the information which could tell us how many website
contains audible autoplay media, but there is no way to get this information on current API desigin.
Therefore, I would like to send a new notification when autoplay occurred.
The extension code could get the information by following way,
```
Services.obs.addObserver((subject, topic, data) => {
// DO SOMETHING
}, "AudibleAutoplayMediaOccurred");
```

Before this change, we accessed the browser URL in the following ways:
- "chrome://browser/content/browser.xul"
- "chrome://browser/content/" (which redirects to chrome://browser/content/browser.xul)
- Services.prefs.getCharPref("browser.chromeURL") which returns "chrome://browser/content/"
- getBrowserURL() from utilityOverlay.js

Make URLBarSetURI more explicit about what it's looking for in `value`,
and ensure the tabbrowser's progress listeners reset the userTypeValue if it's
empty already and there's a same-site document change.

In practice this is an easy fix, just clear the icon when the page first changes
to a new URL. In practice that breaks our hack for setting an early favicon for
certain in-content pages so we have to workaround that somewhat.

Summary:
This moves the load of favicons into the content process. We use the same logic
for finding favicons (based on waiting until none have shown up for a short
time) but then load the favicon and convert it to a data uri which we then
dispatch to the parent process. Along the way this fixes asssociating the load
with the tab for WebExtension and devtools, fixes CSP usage for the load, fixes
expiry detection of the favicon and stops us from loading the same resource
twice.
This change also merges the prefs browser.chrome.site_icons and
browser.chrome.favicons leaving just the former controlling favicon loading. It
adds the pref browser.chrome.guess_favicon to allow disabling guessing where
a favicon might be located for a site (at <hostname>/favicon.ico). This is
mainly to allow disabling this in tests where those additional yet automatic
requests are uninteresting for the test.
There are multiple clean-ups that can follow this but this is a first step along
that path.

These probes will register and record (for the duration of the study only):
* When a tab opens.
* When a tab closes.
* When a tab is selected.
