Introduce native support for MacOS ARM64
There's a new program named ape/ape-m1.c which will be used to build an
embeddable binary that can load ape and elf executables. The support is
mostly working so far, but still chasing down ABI issues.

# SYNOPSIS
#
# Universally Linkable Weak Functions
#
# DESCRIPTION
#
# This package contains no-op implementations for (1) synthetic
# compiler surprises and (2) mission-critical core functions, e.g.
# abort(). These functions are designed to work in all addressing
# modes, including real mode. Every package links this. It's at the
# base of the topological order of things.
