In particular:
* Always handle meta viewport in RDM. This fixes bug 1625999 too by
making touch simulation enabled and disabled consistent.
* Restore the resolution to 1 when toggling RDM. This is just simpler,
and we're not keeping around the visual viewport offsets anyways
so...
* Deal with the change more easily, at the same point we switch
scrollbars etc.

If session history in the parent is enabled then session store only works
correctly if the platform collection code is turned on.

This patch modifies the behaviour of loads when the DONT_RETARGET
nsIURILoader flag is set, making them ignore the Content-Disposition
header. This means that loads which cannot trigger downloads will
attempt to display handleable content which would otherwise be
downloaded.
This keeps overall behaviour of object/embed elements more similar to
their behaviour pre-Fission, while allowing them to load attachment PDFs
and Images as-if they were being displayed by a plugin.
This patch does not change the existing behaviour around
unknown/unhandleable resource types in object/embed elements.
In Gecko, object/embed elements are prevented from triggering downloads
or external protocol handlers during their initial load. Other browser
engines can trigger a download for an unknown resource type (or
sometimes an attachment resource).
The new pref dom.navigation.object_embed.allow_retargeting can be
enabled to instead trigger a download when loading these resources
within an object/embed element.

Most are brought over straightforwardly, their Telemetry callsites reworded
to use Glean, with mirroring to the Telemetry probes taken care of by the Glean
Interface For Firefox Telemetry (see the telemetry_mirror property).
There were two special cases: PERF_DOM_CONTENT_LOADED_FROM_RESPONSESTART_MS,
and PERF_DOM_CONTENT_LOADED_MS. Both were removed as they were unused.

This is somewhat complex, untested, never shipped, and predates
fission.
Remove it to simplify the code.

Previously it may have been possible in some edge cases for us to send
`MaybeFireEmbedderLoadEvents` for a non-toplevel frame during docshell
tree teardown.

It has never shipped after being implemented years ago,
and was removed from spec in September 2022:
https://github.com/w3c/webappsec-csp/pull/564
Now skipping navigate-to WPT tests. Filed issue upstream for their future removal:
https://github.com/w3c/webappsec-csp/issues/608
Consensus seems to agree to remove, will do in follow up bug once landed.
Also removed our own tests.
Added a hack in StartDocumentLoad as just removing the navigate-to check call
breaks some inhertiance, see comment for more info.

Minor correction from https://phabricator.services.mozilla.com/D184821.
The definition of "same-origin" used in that patch was that the iframe's origin after navigation is the same as the triggering principal.
This was incorrect.
Instead, the origin of the iframe before navigation should be the same as after navigation, which is the frame's document principal at the time this is called.
Also, I found places where I missed adding the new fields to the loadinfo: LocationBase and nsFrameLoader.
And I added the redirect tainting check and a missing nullcheck before calling SetTriggeringWindowId in nsDocShell.

This patch removes the old docshell timeline and timeline markers codebase and replaces them with equivalent Gecko profiler marker. This patch also fixes Bug 1834143, which is a subset of 1421651.
