vmm: Use struct vcpu in the instruction emulation code.

This passes struct vcpu down in place of struct vm and and integer
vcpu index through the in-kernel instruction emulation code. To
minimize userland disruption, helper macros are used for the vCPU
arguments passed into and through the shared instruction emulation
code.

A few other APIs used by the instruction emulation code have also been
updated to accept struct vcpu in the kernel including
vm_get/set_register and vm_inject_fault.

vmm: Refactor storage of CPU-dependent per-vCPU data.

Rather than storing static arrays of per-vCPU data in the CPU-specific
per-VM structure, adopt a more dynamic model similar to that used to
manage CPU-specific per-VM data.

That is, add new vmmops methods to init and cleanup a single vCPU.
The init method returns a pointer that is stored in 'struct vcpu' as a
cookie pointer. This cookie pointer is now passed to other vmmops
callbacks in place of the integer index. The index is now only used
in KTR traces and when calling back into the CPU-independent layer.

sys/amd64: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
