Bug 1833618 - P2. Replace checking hidden and display:none in formautofill visibility check with element.checkVisibility API r=credential-management-reviewers,sgalich

This patch includes a preference setting that triggers the execution of element.checkVisibility
only when a form contains fewer than 200 eligible address and credit card fields.
This measure has been implemented to avoid potential performance impact that could occur due
to the visibility check running on a large number of elements.

Bug 1833618 - P1. Use browser test for formautofill heuristic tests. r=credential-management-reviewers,sgalich

Bug 1828469, part 2: Moved some logic from `nsRange` to `AbstractRange` to support `StaticRange`s in custom highlights. r=masayuki

With this change, Selections are also registered into StaticRanges,
ultimately making them visible to `nsINode::IsSelected()`,
which is necessary to paint them.

Bug 1828469, part 1: Prepare `RangeBoundaryBase`  to be able to handle non-`MutationObserver` Range classes. r=masayuki

In order to support `StaticRange`s, which are not `MutationObserver`s, RangeBoundaries need to have an alternative way of ensuring that `mRef` points to the correct node.
This is now done by validating `mRef` every time `Ref()` is called using the parent and offset.
For performance reasons, this is disabled by default and should only be used for `StaticRange`s.

This patch eliminates the race that bug 1809672 points out, and as a bonus it
significantly reduces the number of main thread hops.

This patch creates the desktop capture thread only once needed, and then passes
it to the TabCapturerWebrtc ctor so its threading members can be const.

This is on par with other DesktopCapturer implementations.

This fixes an assertion failure in ~ScreenCapturerMac() which checks that it
runs on the capture thread.

Differential Revision: https://phabricator.services.mozilla.com/D176295

Since we now know FocusOnSelectedSource will only be called after StartCapture()
there is no need for it to be able to create a capturer. This means
EnsureCapturer() has only one caller and can be inlined into StartCapture().

Note that this patch breaks the (verbose) capturer creation logic out to a
static function, but mCapturer and mCaptureThread assignment happens exclusively
in StartCapture().

Bug 1809672 - In MediaManager call FocusOnSelectedSource only after the device successfully started. r=karlt

This will not only benefit the assumptions that can be made on the backend
side. It also means we will not shift focus to an external window in case a
window capture fails to start, of if an audio device that is part of the same
request fails to start.
