Issue #80- De-unify gfx/layers

Excludes layers/ipc/CompositorBridgeParent and CrossProcessCompositorBridgeParent
because the latter purposely uses functions implemented in the former.
See also code comment in CrossProcessCompositorBridgeParent.cpp

Note: likely dead code for us anyway; likely not worth investing in to solve.
