common/sfc_efx/base: support MAC address edit actions in MAE

In a tunnel packet, these actions affect the inner header if
action DECAP is set; otherwise, they affect the outer header.

Adding these actions is done in two steps: add the action to
the action mask and indicate the MAC address entry ID to use.
This allows the user to check the order of actions first and
allocate resources when time comes to enable the action rule.

common/sfc_efx/base: support NIC DMA memory regions API

NIC DMA memory regions API allows to establish mapping of DMA addresses
used by NIC to host IOVA understood by the host when IOMMU is absent
and NIC cannot address entire host IOVA space because of too small
DMA mask.

The API does not allow to address entire host IOVA space, but allows
arbitrary regions of the space really used for the NIC DMA.

A DMA region needs to be mapped in order to perform MCDI initialization.
Since the NIC has not been probed at that point, its configuration cannot
be accessed and there an UNKNOWN mapping type is assumed.

Provide helper function to compose multi-host aware PCIe
function M-port selector.

The firmware expects mport selectors to use different sets of values to
represent a PCIe interface in mport selectors and elsewhere. In order to
avoid having the user perform the conversion themselves, it is now done
automatically when a selector is constructed.

In addition, a type has been added to libefx for possible PCIe
interfaces.
This is done to abstract different representations away from the users.

Allow to support matching traffic coming from an arbitrary PCIe
end-point of the NIC and redirect traffic to it.
