OS print drivers/devices know nothing about page dimensions unless we tell
them. Previously, the physical page dimensions (including orientation) have
always been the same, so communicating their dimensions once at the start of
a print has been enough. In preparation for supporting different "physical"
page dimensions (in the immediate future only different page orientations) when
we save to PDF, we need to have the infrastructure to pass dimensions through
on a page-by-page basis. This patch adds that.

None of the PrintTarget subclasses do anything with this extra information yet,
but in a follow-up patch PrintTargetPDF will use this information to create
PDFs with mixed page orientations.

It's not clear to me why specializing nsCOMPtr<nsISupports> is
particularly useful, and this removes a lot of code, bringing us closer
to unifying nsCOMPtr and RefPtr.

The changes in other places are needed because we used to allow
nsCOMPtr<nsISupports> to implicitly coerce to nsISupports even for
rvalue references.

Bug 1704954 disabled DirectComposition for users with NVIDIA graphics
hardware and mixed monitor refresh rates on Windows 10 and 11, as a
mitigation for bug 1638709. However, that bug is almost -- perhaps
entirely -- unknown on Windows 11 (q.v. for details), and the fallback
path it uses has been shown to cause issues there (bug 1763981).

Restrict the mitigation to only occur on Windows 10, where bug 1638709
is exhibited, but where no issues with the fallback path are known.

This also effectively reverts bug 1816001, which it obviates.

It creates no range `Selection` if `mSelection` has not been emplaced.
However, we don't want `Selection` in the case because `mText` may be nothing
and that violates the dependency.  Therefore, it should stop creating
`Selection` in the case.

Note that first character rect will be cached later even if there is no
`Selection`.  However, this should not occur in usual case because `focus`
notification should've already initialized `mText` and `mSelection`.

Differential Revision: https://phabricator.services.mozilla.com/D178731

Currently, `PuppetWidget` calls `ContentCacheInChild::CacheSelection` directly.
However, `mText` can be `Nothing` or `mText` can be outdated, but `mSelection`
becomes the latest one.  Therefore, we may notify the parent process with
invalid data combination.

The callers in `PuppetWidget` are:
1. `NotifyIMEOfCompositionUpdate`
2. `NotifyIMEOfPositionChange`

I think that the former does not need to cache anything here because
`IMEContentObserver` should've updated the text/selection changes.  However,
stopping caching everything at this point is risky.  In the most cases, outdated
data appears as odd IME UI position.  Therefore, let's keep updating only caret
and text rectangles.

The latter is reported with new crash reports which is crashed by a
`MOZ_DIAGNOSTIC_ASSERT` failure added by the previous patch.  In the case,
if `mText` and `mSelection` has not been cached, we don't need to notify
the parent process with them because they will be sent later.  And also even
if they are not available, it may be useful that the character rectangles not
related to `Selection` (e.g., the first character rect).  Therefore, let's
keep caching same things as the former case.

Therefore, this patch makes `CacheSelection` a private method and add
`CacheCaretAndTextRects` for them.

There are some crash reports crashed in TSF module which may be caused by
passing invalid selection range (e.g., out of bounds of text).  However,
the cache is created in the child process and that causes the invalid cache
creation does not appear in the crash reports.  Therefore, let's try to
crash as soon as possible if `ContentCache` has invalid data.

Note that this does not detect all of the invalid cases because it's hard to
(re-)understand the edge cases.  Therefore, this tries to detect the cases
checked in `ContentCacheInParent::HandleQueryContentEvent` (*1) and some other
obvious odd cases.
