MANUAL PUSH: Hopefully trivially fixes some orange CLOSED TREE.

We weren't doing it. I want to see if it helps with some flickering
intermittents with the patch of bug 1718220.

Not sure how to reliably test this.

This patch is a non-functional change. It overloads some WebIDL methods

This patch is a non-functional change which allows the shutdown observer
to be overridden (since workers have a different mechanism). It also
fixes a static counter to be atomic, and adds mOffscreenCanvas to the
cycle collection tracking.

RemoteImages provides the capability to download and cache images to Firefoxen
off of release trains, e.g., to be used in Nimbus experiments. RemoteImages only returns
blob URIs to avoid allowing file: URIs in Content Security Policy for chrome
documents.

Images are cached for a maximum of 30 days, after which they will be deleted.

The function was returning true as long as the passed element
was an iframe and EFT was enabled.
But if the passed iframe was blocked by a CSP rule, it would
still return true, although we wouldn't actually have a dedicated
document, nor a target, for that iframe, which would lead to
issues in the inspector when trying to fetch the iframe children.
We fix this by adding a new `isFrameBlockedByCSP` util, which  uses
`nsIContentPolicy#shouldLoad` with the iframe url so we can check if the iframe
is blocked by CSP, and in such case, return false.
We're also using this new function in the `NodeActor#form` method to set a `numChildren`
of `0` when the iframe is blocked (so in the inspector, the expand icon will be
hidden for the element), as well as in `WalkerActor#_getChildren` to return an
empty array when called with an iframe blocked by CSP.

A new test is added to check the iframe nodeFront properties and usage of
`WalkerFront#children` with those. We allow to set a specific pref to bypass
the guard in the children method in order to properly check that the root issue
of a given bug was fixed.
