Reland "Send dropEffect attribute on drag and drop events"

This is a reland of commit 0542983115c4ccbaa2b1dd15faff2675d520bbeb

Reason for reland: This CL was erroneously assigned blame for flakiness
in some tests Drag and Drop browser tests in chromeos and linux. See
bug: https://crbug.com/442927728

Original change's description:

Send dropEffect attribute on drag and drop events

This CL implements the dropEffect attribute in the dataTransfer property
in drag and drop event to match the spec.
https://html.spec.whatwg.org/multipage/dnd.html

The attribute is currently not being set, defaulting to "none" on all
events.

Many existing tests were updated to pass with the new implementation.
Notably, the default dropEffect for some "effectAllowed" attributes has
been changed to match the defaults in the table found in "6.11.4 The
DragEvent interface" in the spec. (defaulting to copy whenever copy is
available, and to link if link is available)

[Masonry] Expand grid template track definitions

In grid, grid-template* computes to its expanded track definition. In
Masonry, we were not expanding these, since ComputedStyleUtils:: ValueForGridTrackList() only supported LayoutGrid. This change adjusts
this method to a template that takes either LayoutGrid or LayoutMasonry
and ensures that both classes support the methods needed for
ComputedStyleUtils::ValueForGridTrackList().

This also required updating the grid-template* properties to be layout
dependent if masonry or grid, otherwise, we didn't end up having access
to LayoutData in ComputedStyleUtils::ValueForGridTrackList().

A number of wpt tests that relied on this are now passing for intrinsic
auto repeats, and a few computed style wpts were added for intrinsic
auto repeats as part of this change. Some of which had the wrong
expectation file, so those have been updated, too.

There is one test marked as failing because we are resolving %'s to a
value I wouldn't expect. There was also one crashing when getting the
number of intrinsic auto repeats. These failures are unrelated to this
change, so I will investigate these in a separate CL.

Add support for drag-and-drop tests on scrollbars

This expands the drag-and-drop test helpers to support cases where the
drop target is a scrollbar, not just the center of an element. It fixes
existing tests designed to exercise drag-and-drop interactions with
element scrollbars, ensuring they now test the correct scenario. This
change adds movePointerToScrollbar, and other related helper functions.

[CodeHealth] Refactor pointerevent_pointerrawupdate.https.html

This is a no-op CL to improve the WPT for secure contexts:

• Replaces the state-machine based assertions with a simple event
  order assertion, which also adds the missing coverage for "one
  pointerrawupdate per pointermove" (as per
  https://w3c.github.io/pointerevents/#the-pointerrawupdate-event ).
• Adds the coverage for global event listeners.
• Ports old-style tests to promise_tests and "use strict".

(Confirmed manually that Firefox passes the test before and after.)

Don't try to sort complex-typed CSS math operations based on its unit

When simplifying math expressions for sum or product we should normally
sort each component of the expression based on its type, e.g. 1rem + 1px

• 1em should become 1em + 1px + 1rem. However, when we have a
  complex-typed expression (e.g. 1rem / 1px * 1px) the spec is not clear
  about which type should be used for sorting. This leads to the crash in
  our code when we call ResolvedUnitTypeForSimplification, as that
  function doesn't know how to get a type of a typed expression.

So, this CL treats such complex-typed expressions as other expressions
that can't be sorted based on its type (such as css math functions, e.g.
sign()), meaning that sorting first puts numeric values sorted by their
alphabetical order of units and then it puts every other expression in
the same order it appeared in the original expression.

Also, this CL moves calls to ResolvedUnitTypeForSimplification close to
where it will be used (with numeric literals with double value), so that
for complex-typed expressions we don't call that function.

The test case also has 1px * 1px / 1px which should be simplified to
just 1px, but that is out of the scope of this CL.
