[SF] Introduce VirtualDisplayId

This change introduces a new class VirtualDisplayId which is
inherited by HwcVirtualDisplayId and GpuVirtualDisplayId.
HwcVirtualDisplayId replaces the current ids assigned to
virtual displays backed by HWC. GpuVirtualDisplayIds are random
generated IDs assigned to non HWC virtual displays, which currently
don't have IDs. This way all compositionengine/Display and
DisplayDevice objects have a DisplayId.

The logic for ID generation is encapsulated in DisplayIdGenerator.h.
