[PATCH v21 net-next 03/12] net/nebula-matrix: add channel wire opcode enum definitions

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

From: illusion wang <illusion.wang@nebula-matrix.com>

Add enum nbl_chan_msg_type to nbl_def_channel.h, which defines all
PF/VF/firmware channel wire opcodes used for inter-component mailbox
communication.

Each enumerator ordinal acts as the wire-format message ID. These opcodes
are stable across firmware and driver versions; reordering or inserting
new entries before NBL_CHAN_MSG_MAILBOX_MAX will break cross-version
interoperability.

This commit only introduces the opcode ID enumeration. Message data
structures and full channel layer logic are added in subsequent separate
patches. Explicit fixed numeric values for each opcode will be assigned
in a follow-up patch to avoid accidental opcode renumbering.
