WindowServer: Separate physical resolution from scaling factors

Browse source 
Physical hardware doesn't care about scale factors as this is a concept
being related to WindowServer and userland applications. To ensure we
provide the correct display resolution details to HardwareScreenBackend
objects, we must keep a separate Gfx::IntRect object that reserve the
correct details.
