This needs to dumb down the parsing in order to match what we do in Gecko and
pass more tests.
The remaining tests are just because of calc() in media queries and "or" media
expressions.

We only need to do this when display changes from none to non-none, so handle it
explicitly when computing the cascade requirement.
This patch also removes a few conditions that are redundant because they're
handled also by the cascade requirement check, like the initial styling.
It's out-of-band data I never liked, and the code has changed enough from when
it was introduced, that now all of the information it stores can be local.
This is only useful to avoid restyling NAC subtrees, but _not_ for ::before or
::after, in most cases. These subrees are small, and reframing is also not too
common, so I don't think it warrants the complexity.

We already remove all change hints down the tree when finding a reframe hint
using ClearServoRestyleFromSubtree in ServoRestyleManager, so this is useless.
