Check if presentationTime exists before asserting its value since it's an optional attribute (#51536)

In PaintTimingMixin, presentationTime is an optional attribute:

[Exposed=Window]
interface mixin PaintTimingMixin {
    readonly attribute DOMHighResTimeStamp paintTime;
    readonly attribute DOMHighResTimeStamp? presentationTime;
};

In other tests we always have this if ("PresentationTime" in entry)
checks to make sure that they are present. But it seems like we missed
this test.

Fix WPT scroll-start-overflow-toggled.tentative.html to properly await a requestAnimationFrame callback.

The pattern that the test was using, "await requestAnimationFrame", does
nothing because requestAnimationFrame doesn't return a Promise that could
be awaited.

To actually use 'await' to allow a requestAnimationFrame tick to pass, you need
to add your own Promise that gets resolved in requestAnimationFrame's callback,
as amended in this patch.

Make WhiteSpaceVisibilityKeeper::MergeFirstLineOfRightBlockElementIntoAncestorLeftBlockElement ignore empty Text nodes when scanning first character of the right block

Although, the empty text should've been removed, but it may happen without the
normalization. Therefore, the lambda should keep scanning the first visible
char with ignoring empty Text nodes.

Additionally, there are similar methods which have the same lambda. Therefore,
this fixes them too.

I think we should make the scanner method take an option parameter to ignore
empty Text in a follow up bug.

Make input element display-inside always flow-root

Column rule painting for wrapped columns.

Not perfect, but hopefully good enough until we get CSSGapDecoration
(which is also required for row rules).

Refactor BoxFragmentPainter::PaintColumnRules() to avoid duplicated
logic for horizontal and vertical writing mode, and add support for
multiple consecutive rows (without intervening spanners). Also paint
column rules in the row gaps.

Add some getters for start offsets and sizes to LogicalRect.
PhysicalRect already has them.

Translator: Add inputQuota and measureInputUsage

Adds the inputQuota and measureInputUsage for translator. Always returns
+Infinity for inputQuota and 0 for measureInputeUsage since our
implementation doesn't have any limits. Only thing not implemented is the
abort signal.

[Selection] delegated target text control are mouse event handled

We add the feature DelegatesFocusTextControlFix,
which fixes this case: when the mouse target element is a shadow host
with delegatesFocus, but its focusable area is a text control element.

Currently, this text control element will be marked as focused and not
handled. The selection will be set on where the click happened.
That is wrong because, in this case, focus and selection should both be
on the text control.
We fix this by updating the logic in MouseEventManager::HandleMouseFocus

1. If focusable area is already focused, no need to re-focus and return
   not handled so selection can be set where click happened.
2. Else, if focusable area is a text control, focus it and return
   handled so selection stays on it.
3. Else, focus it and return not handled so selection can be set where
   click happened.
