The headers were originally written in Mesa, imported to the kernel, and improved upon in vc4-gpu-tools. These come from the v-g-t copies and will replace the Mesa and v-g-t copies, and hopefully be used from new tests in igt, as well.
v2: Fix linking against libdrm_intel instead of libdrm. v3: Drop Libs and Cflags since they'll be inherited from libdrm.
