acpi_spmc: Add system power management controller driver

Add SPMC (system power management controller) driver as acpi_spmc. This
is the device which provides the LPI device D-state constraints and
allows for OSPM to send S0ix/modern standby entry/exit notifications.
This supports the original Intel DSM
(https://uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf,
untested), the AMD DSM (tested), and the Microsoft DSM (tested).

Before entry, acpi_spmc_check_constraints is called to notify of any
violated power constraints. This will use acpi_pwr_get_state to get
current device D-states when that gets added back.

bpf: modularize ifnet(9) part of bpf

Imagine that bpf(9) tapping can happen at any point in the network stack,
not necessarily at interface transmit or receive. To achieve that we need
a thin layer of abstraction defined by struct bif_methods, that defines
how generic bpf layer works with a tap point of this kind.

Implement ifnet(9) specific methods in a separate file bpf_ifnet.c. At
this point there is 100% compatibility for all existing interfaces, there
is no KPI change, yet. The legacy attaching KPI is layered over new ifnet
agnostic KPI. The new KPI may change though, as we can implement multiple
DLTs per single tap point in a prettier fashion.

The new abstraction layer allows us to move all the 802.11 radio injection
hacks out of bpf.c into ieee80211_radiotap.c, so do that immediately as a
good proof of concept.

kern: Introduce kexec system feature (MI)

Introduce a new system call and reboot method to support booting a new
kernel directly from FreeBSD.

Linux has included a system call, kexec_load(), since 2005, which
permits booting a new kernel at reboot instead of requiring a full
reboot cycle through the BIOS/firmware. This change brings that same
system call to FreeBSD. Other changesets will add the MD components for
some of our architectures, with stubs for the rest until the MD
components have been written.

kexec_load() supports loading up to an arbitrary limit of 16 memory
segments. These segments must be contained inside memory bounded in
vm_phys_segs (vm.phys_segs sysctl), and a segment must be contained
within a single vm.phys_segs segment, cannot cross adjacent segments.

cxgbe: Support for NIC KTLS transmit on T7 adapters.

Unlike NIC KTLS support on T6, T7 is able to reuse the existing TSO
functionality directly, including trimming the output of the crypto
engine before it is passed on to TSO. This is much simpler and does
not require the use of bypass pseudo-connections in the TOE engine.
Among other things this permits arbitrary TCP options (including the
full range of possible TCP timestamp values) while also avoiding
various edge cases where parts of a requested TCP packet could not
always be transmitted (e.g. partial trailers). This implementation
also permits NIC KTLS to be used in parallel with TOE.

This version does not yet support connections over a VF (specifically
the ktls_tunnel_packet function needs to handle the VF work request),
nor does it support VxLAN offload.

cxgbe: Move the STAG and PBL memory pool arenas to the base driver

Both RDMA (iw_cxgbe) and NVMe offloads use TPT table entries to map
transaction tags in incoming PDUs to buffers in host memory permitting
direct placement of received data into host memory buffers avoiding
copies (iSCSI offload uses a different scheme for mapping tags to host
memory). Move the vmem arenas for the supporting card memory regions
from iw_cxgbe to the main driver so they can be shared with the NVMe
offload driver. In addition, add some helper routines for
constructing work requests to update TPT table entries.
