common/sfc_efx/base: support UDP tunnel operations for EF100

EF100 uses VNIC encapsulation rule MCDI for configuring UDP
tunnels in HW individually. Use busy added and removed states
of UDP tunnel table entries for the implementation.

common/sfc_efx/base: introduce states for UDP tunnel entries

UDP tunnel reconfigure operation takes UDP tunnel table, which contains
entries that need to be applied to HW. This approach does not retain
information about what entries were removed or added, which is required
for Riverhead.

Add states to the table entries to indicate add or remove operations.
On tunnel reconfiguration added and removed entries become busy to
indicate that the entries are currently configured and to prevent add or
remove operations from other threads. After tunnel reconfiguration is
complete, the states are reset - added entries become applied and
removed entries are purged from the table.

common/sfc_efx/base: introduce UDP tunnel destruct operation

The procedures for destroying UDP tunnels are NIC family specific,
so they should be implemented separately for each of them.

Check for supported UDP encapsulation is removed from generic
operations since it is no longer used by the generic libefx API.

net/sfc: introduce common driver library

Move libefx (base driver) into common driver.

Prepare to add vDPA driver which will use the common driver as well.
