sfxge(4): support filters for encapsulated packets

This supports filters which match all unicast or multicast
inner frames in VXLAN, GENEVE, or NVGRE packets.
(Additional fields to match on can be added easily.)

sfxge(4): fix efx_filter_supported_filters API

The previous API had various problems, including the length of the
caller provided buffer not being specified, no means being available
to discover how big the buffer needs to be, and a lack of clarity of
what the resulting list contains.

To fix it:
- add the buffer length as a parameter
- if the provided buffer is too short, fail with ENOSPC and return the
required length
- ensure that the list contents are valid and add comments
describing it

It is safe to change this API as, unsuprisingly, it has no users.

sfxge(4): split EFX_FILTER_MATCH_LOC_MAC_IG back into separate flags

The flag EFX_FILTER_MATCH_LOC_MAC_IG to represent filtering on the
individual/group bit of the MAC address (with the two cases being
distingusished by the MAC address in the filter specification) was
introduced to mirror the Linux driver filtering code, but the
implementations are different enough anyway that it isn't of much value.

Having separate flags for unknown unicast and multicast simplifies
the code and allows the set of flags to match those used by MCDI.

It will also makes it easier to report whether these filters are
supported.

In the MCDI definitions, the unknown multicast and unicast flags have
the values 0x40000000 and 0x80000000 respectively, and so using the
same values for simplicity requires 32 bits in the filter specification
to store the flags. This means the structure is now a little bigger
than 64 bytes, but filters are not often used on critical paths so this
shouldn't have much impact - on Linux they are also bigger than they
used to be.

sfxge(4): cleanup: add efsys_lock_state_t for type of state param in EFSYS_LOCK()

This allows the common code to use the correct type for the lock state
local variable passed to EFSYS_LOCK() and EFSYS_UNLOCK().

On Windows, this allows warning supression pragmas to be removed.

sfxge: add prefast annotation to common code return types

Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).

This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.
