net/mlx5: Verify support for scheduling element and TSAR type

[ Upstream commit 861cd9b9cb62feb244b8d77e68fd6ddedbbf66e9 ]

Before creating a scheduling element in a NIC or E-Switch scheduler,
ensure that the requested element type is supported. If the element is
of type Transmit Scheduling Arbiter (TSAR), also verify that the
specific TSAR type is supported.
