anv: check cmd_buffer is on a transfer queue more properly

The queueFlags of the associated queue may have more flags than just the
type of queue it is, based on what that queue supports, like sparse or
protected content. Check that the queue is a blitter engine instead.

Fixes a bunch of dEQP-VK.api.copy_and_blit.core.*_transfer on MTL with
ANV_SPARSE=0

Fixes: 17b8b2cffd ("anv: Add support for a transfer queue on Alchemist")
