lib/rendercopy: Add gen4/5 rendercopy

Add rendercopy implementation for gen4/5. Basic structure
copied from the gen6 implementation, and the gen4/5 specific
bits were mostly lifted from sna.

v2: Renamed registers definitions, which are GEN4 specific
to include that prefix (Lukasz)
v3: Rebase and checkpatch
