[igt-dev] [PATCH i-g-t 1/2] tests/i915/gem_ccs: Check ctrl-surf-copy in new context

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

From: Apoorva Singh <apoorva1.singh@intel.com>

Verify ccs data is binded to physical memory by using
XY_CTRL_SURF_COPY_BLT command in separate context.

v2: add separate allocator handle for new context (Zbigniew)
