[PATCH v4 1/8] drm/amdgpu/mes_userqueue: refactor mqd_update into per-IP helpers

[Jesse Zhang <Jesse.Zhang@amd.com>]

Split the inlined compute path out of mes_userq_mqd_update() into
mes_userq_compute_mqd_update() and turn the former into a dispatcher that
switches on queue_type, giving other IPs an obvious place to hook in.

No functional change.
