Revert 272635 "cc: Examine layers to determine if we're ready to..."

Caused layout test failures and out-of-memory errors on several Mac
bots on the Blink waterfall. See Issue 375206.

BUG=375206

> cc: Examine layers to determine if we're ready to activate.
> 
> This introduces a new mechanism for determining when
> we're ready to activate the pending tree. The tile
> priority is still used to determine when it's worth
> waking up the compositor thread and evaluating if
> we can activate. However, the actual check that
> determines if we're ready to activate doesn't rely
> on the state of scheduled raster tasks but is a
> synchronous call on each layer.
> 
> The result is a pending tree activation mechanism that
> is much easier to debug and validate for correctness,
> while still providing the performance benefits of the
> old mechanism by taking the "required to activate" field
> of the tile priority into account when scheduling tasks.
