[PATCH v8 net-next 09/11] net/nebula-matrix: add Dispatch layer implementation

["illusion.wang" <illusion.wang@nebula-matrix.com>]

This patch introduces a control-level routing mechanism for the Dispatch layer.
Two routing ways:
(Direct path):Dispatch Layer-> Resource Layer -> HW layer
The Dispatch Layer routes tasks to Resource Layer, which may interact
with the HW Layer for hardware writes.

(Channel path):Dispatch Layer->Channel Layer
The Dispatch Layers redirects hooks to the Channel Layer.

Proposed Solution:
Introduce a control level mechanism with two components:
1. Interface-declared control levels
   Each operation interface declares its required control level
(e.g., 'NET_LVL' for networking, 'CTRL_LVL' for management).

2. Upper-layer configured control levels
   The upper layer (e.g., PF driver) dynamically configures which control
levels should use the direct path.

Example:
Regular PF
Configures 'NET_LVL' at Dispatch layer
  All 'NET_LVL' operations use direct path; 'CTRL_LVL' operations go via channel.
Management PF
  Configures both 'NET_LVL' and 'CTRL_LVL'
  All operations use direct path.
