script|layout: Do not force restyle when doing script queries (#37677)

Instead of doing a restyle whenever layout is requested, only do one if
script believes that the `Document` has changed in a way that needs a
restyle. In addition, track the different reasons this might be the
case. This will be used later to provide better debugging output.

In layout, when a restyle isn't requested, provide:
 - an early return if layout is up-to-date enough for the reflow goal.
 - skipping restyle and reflow if it isn't necessary.

Testing: This should not change observable behavior, and thus is covered
by existing tests.
