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

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.
