commone files and make file changes to enable the ARM64 FreeBSD

This reverts commit 9ef7df022a ("hyperv: Register hyperv_timecounter
later during boot") and adds a comment explaining why the timecounter
needs to be registered as early as it is.

Previously the MSR-based timecounter was registered during
SI_SUB_HYPERVISOR, i.e., very early during boot, and before SI_SUB_LOCK.
After commit 621fd9dcb2 this triggers a panic since the timecounter
list lock is not yet initialized.
The hyperv timecounter does not need to be registered so early, so defer
that to SI_SUB_DRIVERS, at the same time the hyperv TSC timecounter is
registered.

error in the function hypercall_memfree(), where the wrong arena was being
passed to kmem_free().
Introduce a per-page flag, VPO_KMEM_EXEC, to mark physical pages that are
mapped in kmem with execute permissions. Use this flag to determine which
arena the kmem virtual addresses are returned to.
Eliminate UMA_SLAB_KRWX. The introduction of VPO_KMEM_EXEC makes it
redundant.
Update the nearby comment for UMA_SLAB_KERNEL.

FreeBSD VM can't boot up on Hyper-V after the recent malloc change in
r335068: Make UMA and malloc(9) return non-executable memory in most cases.
The hypercall page here must be executable.
Fix the boot-up issue by adding M_EXEC.
