net/mlx5: Add support for new scheduling elements

Browse source

Introduce new scheduling elements in the E-Switch QoS hierarchy to
enhance traffic management capabilities. This patch adds support for:

- Rate Limit scheduling elements: Enables bandwidth limitation across
  multiple nodes without a shared ancestor, providing a mechanism for
  more granular control of bandwidth allocation.

- Traffic Class Transmit Scheduling Arbiter (TSAR): Introduces the
  infrastructure for creating Traffic Class TSARs, allowing
  hierarchical arbitration based on traffic classes.

- Traffic Class Arbiter TSAR: Adds support for a TSAR capable of
  managing arbitration between multiple traffic classes, enabling
  improved bandwidth prioritization and traffic management.

No functional changes are introduced in this patch.
