mlx5: Fix HCA cap 2 query

Previously we were trying to set hca_cap_2 without checking if
sw_vhca_id_valid max value, which is the only settable value inside
hca_cap_2, and seeing that we dont have driver support for sw_vhca_id
yet there is no need to set hca_cap_2 at all, it is enough to query it.

mlx5: Add raw ethernet local loopback support.

Currently, unicast/multicast loopback raw ethernet (non-RDMA) packets
are sent back to the vport. A unicast loopback packet is the packet
with destination MAC address the same as the source MAC address. For
multicast, the destination MAC address is in the vport's multicast
filter list.

Moreover, the local loopback is not needed if there is one or none
user space context.

After this patch, the raw ethernet unicast and multicast local
loopback are disabled by default. When there is more than one user
space context, the local loopback is enabled.

Note that when local loopback is disabled, raw ethernet packets are
not looped back to the vport and are forwarded to the next routing
level (eswitch, or multihost switch, or out to the wire depending on
the configuration).

Update user access region, UAR, APIs in the core in mlx5core.

This change include several changes as listed below all related to UAR.
UAR is a special PCI memory area where the so-called doorbell register and
blue flame register live. Blue flame is a feature for sending small packets
more efficiently via a PCI memory page, instead of using PCI DMA.

- All structures and functions named xxx_uuars were renamed into xxx_bfreg.
- Remove partially implemented Blueflame support from mlx5en(4) and mlx5ib.
- Implement blue flame register allocator.
- Use blue flame register allocator in mlx5ib.
- A common UAR page is now allocated by the core to support doorbell register
writes for all of mlx5en and mlx5ib, instead of allocating one UAR per
sendqueue.
- Add support for DEVX query UAR.
- Add support for 4K UAR for libmlx5.
