[cc] Color evicted vs. invalidated checkerboard tiles differently

[cc] Color evicted vs. invalidated checkerboard tiles differently

If --show-debug-layer-borders are on, tint checkerboards differently.

* Light red = texture backing for tile was evicted or never painted
* Light blue = we have a texture backing, but it's been invalidated

I thought I had run cc_unittests, but apparently not.  Also, since the CQ
doesn't run cc_unittests, the previous patch landed without any trouble.

The main change is that tests were checking "hasTileAt" and since invalidated
but not evicted tiles are now synced, that this was wrong.  I changed them all
to use hasTextureIdForTileAt and then renamed that to hasResourceIdForTileAt.

I think the CQ should run cc_unittests now thanks to
