The old code didn't dereference the layer index from the
bitmask which caused it to subtract layers it shouldn't
have. In order to do this right, we need to look at the
layer index corresponding to the bit in the id_set to
ensure we're excluding the correct layers.
BUG=None
TEST=Precomposition doesn't draw over dedicated layers

This patch changes two things with respect to protected layers:
1- It provisions the HW plane in the correct position. ie: if
the background layer is slated for a HW plane, it will be
placed on the primary layer and the protected layer will be
placed on top of it.
2- It punches a hole through the precomposite and squash layers
such that when they are placed on top of the protected layer,
they do not obstruct it.
BUG=b/27502957
TEST=Tested on smaug with multi-window with a variety of different
layouts and visible layers

It is spelled "separate", not "seperate".
