[Intel-gfx] igt tests/rendercopy: Add option to test resource streamer functionality

[Abdiel Janulgue]

This patchseries tests a resource streamer feature called hw-generated binding tables,
which can be enabled from userspace. It is essentially a newer format that uses the hw to
generate and submit binding tables to the GPU. It uses the basic rendercopy test to toggle
the feature on and off and to verify if the resulting data is still correct.
