TileGrid creates new cohorts even when not using temporarilyRetainTileCohorts mode
https://bugs.webkit.org/show_bug.cgi?id=166440

Reviewed by Simon Fraser.

No new tests.

* platform/graphics/ca/TileGrid.cpp:
(WebCore::TileGrid::revalidateTiles):
If we are not temporarily retaining unparented tile cohorts (e.g. on
iOS WebKit2), instead immediately removing all tiles that would go into
the new cohort, avoid starting the cohort at all.
