Kartikaya Gupta 395eaf8c66 Bug 1448490 - Make the layers id a struct instead of a uint64_t. r=mattwoodrow
The new struct is in LayersTypes.h, all the rest of the changes are just
replacing existing uint64_t instances with the new LayersId struct.

Note that there is one functional change, in
CompositorBridgeParent::DeallocPWebRenderBridgeParent, where we now
correctly convert the PipelineId to a LayersId before using it to index
into sIndirectLayerTrees, whereas before we were incorrectly just using
the mHandle part of the PipelineId.
