Fallback to check all pages when getting the pageIndex of FieldObjects

[Editor] Avoid to unselect some editors when the main window is focused

When several editors are selected and the window loses and then gets back its focus,
the previously focused editor is triggering its focus callback making it the only
selected one.
This patch aims to avoid triggering the focus callback called when the main window
gets its focus back.

[Editor] Move an the editor div in the DOM once a translation with the keyboard is done

When moving an element in the DOM, the focus is potentially lost, so we need to make sure
that the focused element before the translation will get back its focus after it.
But we must take care to not execute any focus/blur callbacks because the user didn't
do anything which should trigger such events: it's a detail of implementation. For example,
when several editors are selected and moved, then at the end the same must be selected, so
no element receive a focus event which will set it as selected.

[Editor] Fix the resizing of an editor when it's rotated (bug 1847268)

There are 2 rotation we've to deal with: the viewer one and the editor one.
The previous implementation was a bit complex and having to deal with these
rotation would have potentially increase it.
So this patch aims to simplify the implementation and deal with all the possible
cases.
The main idea is to transform the mouse deltas according to the rotations and then
apply the resizing in the page coordinates system.

[Editor] Change the resize cursors to bidirectional variants

When resizing an editor we're currently using unidirectional cursors, please refer to https://developer.mozilla.org/en-US/docs/Web/CSS/cursor
Given that editors can (generally) be resized to become either smaller or larger, it seems overall more appropriate to use bidirectional cursors to make this clearer to the user.

Note that as mentioned in the MDN article some environments, which seems to apply to e.g. Windows 11, doesn't differentiate between the two cursor formats and simply use bidirectional ones unconditionally.

One additional benefit of these changes is that the relevant CSS rules become slightly more compact.

This has now been enabled unconditionally in Firefox, see https://bugzilla.mozilla.org/show_bug.cgi?id=1814589

For the page-containers in the viewer, this patch should restore the behaviour prior to PR 15770; see e.g. https://github.com/mozilla/pdf.js/pull/15770/files#diff-c48e3561004f5db8f11d5ebab2fd661591222ba911cb4173fbced15f026bac6bL182-L183
Note that these changes this will lead to a tiny bit of movement in some text and annotations reference tests.

Attempt to expose e.g. pdfjsLib globally regardless of how the library is imported (issue 16778)

We obviously don't want to re-introduce any require usage in e.g. the viewer, since we should strive to only use native import statements wherever possible.[1]
Hopefully exposing e.g. the library globally in more cases won't break anything, however it's somewhat difficult for me to imagine all the ways in which third-party users may be accessing the PDF.js library. (Given the lack of a runnable test-case in the issue, I also cannot guarantee that this is enough to fully address the problem.)

---

[1] Ideally we should probably not rely on e.g. pdfjsLib being globally available in the built viewer, and rather always import the library instead.
Unfortunately this would require larger (possibly breaking) changes in the builds that we provide, however note that Firefox only recently got support for import in workers and that Webpack still only have experimental support for outputting "proper" modules.

I've submitted a try run for this commit: https://treeherder.mozilla.org/jobs?repo=try&revision=fef6abdceb1051d1605ec38b3458d93d2cc34f97

All the jobs in the try run succeeded. Like literally all of them, there weren't
even any intermittents. That is pretty surprising to me, so maybe you should double
check to make sure I didn't misinterpret things and that the correct tests ran...

Anyway, I've done all I can, so I'm passing to you to review and land the patch.
When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.
