[PATCH i-g-t v2 1/3] lib/meson.build: Add AMDGPU_USERQ_ENABLED check for user queues

[Jesse.zhang@amd.com]

From: "Jesse.zhang at amd.com" <Jesse.zhang at amd.com>

Detect whether libdrm provides amdgpu_create_userqueue() and define
AMDGPU_USERQ_ENABLED if available. This enables user queue support
when building against newer libdrm while maintaining compatibility
with older versions that lack this function.
