net: enetc: add "Update" and "Delete" operations to VLAN filter table

Add two interfaces to manage entries in the VLAN filter table:

ntmp_vft_update_entry(): Update the configuration element data of the
specified VLAN filter entry based on the given VLAN ID. It uses the
exact key access method to locate the entry.

ntmp_vft_delete_entry(): Delete the VLAN filter entry corresponding to
the specified VLAN ID. It also uses the exact key access method to
identify the target entry.

In addition, introduce struct vft_req_qd to describe the request data
buffer format for Query and Delete actions of the VLAN filter table,
which contains a common request data header and a VLAN access key.
