bhyve: add PCI IDs of Intel GPUs from Linux v6.15
Linux maintains a list of all known PCI IDs for Intel GPUs. We need this list
in the future because the quirks applied by our GVT-d emulation don't work for
the latest generation of Intels integrated graphcis devices. We have to detect
the generation and then apply some generation specific quirks to it.
Fortunately, Linux has macros for each graphic device type making it easy for
us to use that header to detect the generation of the device in the next step.

bhyve: support VBTs which lay outside of the OpRegion
Previously, all of our devices had an OpRegion with a VBT which lays inside the
OpRegion. Unfortunately, the OpRegion has a fixed size and VBTs get more and
more features/settings. A VBT can be larger than the allocated space of 6 KB
inside the OpRegion. For larger VBTs, Intel added two fields to the OpRegion to
report the VBT address and the VBT size. Make bhyve aware of those fields and
put the VBT into the guest memory too.
Unfortunately, Intel forgot to consider virtualization when defining OpRegion
v2.0. OpRegion v2.0 uses an absolute address for pointing to the VBT. This
address is useless in a guest environment. It's possible to patch that.
However, it requires some more work and we can't test it because we have no
test device with this combination. Therefore, we don't want to do that yet
until we have a use case. Fortunately, Intel noticed the issue and from v2.1
onwards, the VBT address is a relative address.

makefs: Implement the collision differentiator for micro ZAPs
In the unlikely event of a hash collision, the collision differentiator
is used to create a unique lookup key for ZAP entries. While the fat
ZAP implementation in makefs implemented this, the micro ZAP
implementation did not, so it's possible to end up with collisions in
directory entries. These are caught deterministically by OpenZFS, but
the result is a panic.
Implement a simple differentiator by simply assigning a unique value to
each ZAP entry. This scheme works since the 16-bit space of
differentiators is larger than the maximum number of entries in a micro
ZAP. (While the on-disk encoding provides 32 bits of space for the
differentiator, the in-memory representation of micro ZAP entries is
smaller.)

cp: Fix improper use of O_PATH.
This does not appear to make any practical difference at the moment, but
technically `O_PATH` means “I'm not going to use this descriptor for any
other purposes than vnode lookups”, so using it to read the directory's
ACLs is improper and might fail in the future.
