intel_batchbuffer: Add utility fuction for supporting 48-bit address relocations in Gen8+
There are Gen8+ instruction which requires 48bit address relocation
(eg: Surface State Address in STATE_BASE_ADDRESS instruction). Add the batchbuffer
utility funcation for the relocation based on Mesa's batch buffer implementation.
