Bug 1769404 - Do not handle invalid message caused by moving tabs between different windows r=gfx-reviewers,aosmond

The problem happened by ProcessWebRenderParentCommands() handling with invalid transaction message. When a Tab is moved between Windows, WebRenderBridgeParent::UpdateWebRender() is called. It update mApi and mIdNamespace. Then all WebRender related resources are freed. Then a message with old mIdNamespace from WebRenderBridgeChild becomes invalid. Then we should not handle the obsoleted message.

Bug 1808155 Part 2: Make VIDEO_LOG note events that will cause the video layer to rebuild. r=mstange

There are only a few things that could cause the video layer to be
rebuilt:
1) The mMutatedSpecializeVideo flag being set.
2) A new layer object being created to host for the video.

This patch more thoroughly documents instances of case 1 by adding
VIDEO_LOG message to anything that sets the mMutatedSpecializeVideo flag.

It also makes some attempt to identify case 2 by adding a VIDEO_LOG
message whenever we destroy a layer that has ever displayed a video
texture. If a log message like this is followed by a message that a new
video layer is created, it is a strong signal that we are unexpectedly
throwing away our external surface handles when we'd like to keep using
them.

Bug 1815552 - Make positioned table parts deal correctly with switching position without being reframed. r=TYLin,layout-reviewers

While looking at the backout, I noticed table parts relied on reframing
on abspos-container-ness changes in a subtle way, see the test, which
fails with the first patch of this bug applied without these changes.

Make the NS_FRAME_CAN_HAVE_ABSPOS_CHILDREN mean the same for table parts
as for everything else. Instead, keep the registration status on each
relevant frame class individually.

Bug 1819279 - [devtools] Switch to a block list of known errors instead of an ignore list r=jdescottes

This patch switches from an ignore list of errors to a block list of the errors
we clearly want to block. We are likely going to regress a lot by missing errors from the ignore list
which shouldn't be blocked as revealed by this BUG. Instead let just block the errors we know about and
let other erros through as most of them are shown with error codes and do not need to be blocked.

`nsIURI` fails to cast to `nsIURL` so we used to get a nil url and
return empty string (e.g. for pathname). As we're able to get the
pathname information from URI, I wonder we can just use it directly
without casting to `nsIURL`. With doing so, we can fix the issue.

If the parent process is very short-living, we can find us shutting down
while the startup had not yet finished. This seems to confuse things up
to the point to have a shutdown hang. There seems to be no easy/reliable
way to interrupt startup, so we should just wait for it to finish.
Note that we can just use the already present `quitApplicationGranted`
blocker as earliest possible shutdown phase to block.
