net/mlx5: fix LACP redirection in Rx domain

[ upstream commit 49dffad ]

When the "lacp_by_user" is not set from the application in bond
mode, the LACP traffic should be handled by the kernel driver by
default.

This commit adds the missing support in the template API when
"dv_flow_en=2". The behavior will be the same as that in the DV
mode with "dv_flow_en=1". The LACP packets will be redirected to the
kernel when starting the steering in the NIC Rx domain.

With this commit, the DEFAULT_MISS action usage is refactored a bit.
In the HWS, one unique action can be created with supported bits set
in the "flag" per port. The *ROOT_FDB and *HWS_FDB flag bits will
only be set when the port is in switchdev mode and working as the
E-Switch manager proxy port. The SF/VF and all other representors
won't have the FDB flag bits when creating the DEFAULT_MISS action.
