Don't invalidate tiling:
- when LCDTextDisallowedReason changes from one reason to another
  as long as PicureLayerImpl::can_use_lcd_text() is the same as
  HighResTiling()->can_use_lcd_text().
- if there is no text, but keep the high res tiling with the existing
  LCD text and raster translation they don't matter without text.

This doesn't fix the root cause of the bug (crrev.com/c/2411492 by
vmpstr@ does), but is just a performance improvement.
