Make thread creation work for CloudABI processes. Summary: Remove the stub system call that was put in place during the system call import and replace it by a target-dependent version stored in sys/amd64. Initialize the thread in a way similar to cpu_set_upcall_kse(). We provide the entry point with two arguments: the thread ID and the argument pointer. Test Plan: Thread creation still seems to work, both for FreeBSD and CloudABI binaries.

#ifndef _CLOUDABI64_UTIL_H_
#define _CLOUDABI64_UTIL_H_
Refactoring: move out generic bits from cloudabi64_sysvec.c. In order to make it easier to support CloudABI on ARM64, move out all of the bits from the AMD64 cloudabi_sysvec.c into a new file cloudabi_module.c that would otherwise remain identical. This reduces the AMD64 specific code to just ~160 lines. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D3974
