Bug 1781759 use media element node principal instead of channel loading principal for cross-origin resource test r=padenot

When the media resource is loaded as a document, the response from the initial
document load gets reused, as an optimization, as an emulated load for the
resource of the media host element in the generated HTML document.
https://searchfox.org/mozilla-central/rev/5644fae86d5122519a0e34ee03117c88c6ed9b47/dom/html/VideoDocument.cpp#114
https://html.spec.whatwg.org/multipage/browsing-the-web.html#read-media
The loadingPrincipal of the initial channel comes from the parent document,
and so is not useful to determine whether the response is cross-origin with
the media element.

This change makes the cross-origin test on the initial document load
consistent with subsequent requests on the same resource and non-document
loads, which already use the node principal for the loadingPrincipal.

Bug 1785311 - Make `EditorBase::InsertTextIntoTextNodeWithTransaction` update insertion point after executing the transaction r=m_kato

Before the fix of bug 1758420, `TextComposition`'s text node and offset in it
are updated at creating `CompositionTransaction`.  However, it's now put off
until getting the mutations.  Therefore, it always unsets `pointToInsert` at
first time of the composition and fails to notify the listeners.

This patch makes it retrieve the result after calling `DoTransactionInternal`
and handle the post processing with the new point.
