tests/functional/test_mem_addr_space: Use set_machine() to select the machine

By using self.set_machine() the tests get properly skipped in case
the machine has not been compiled into the QEMU binary, e.g. when
"configure" has been run with "--without-default-devices".

tests/functional: skip memaddr tests on 32-bit builds

If the QEMU binary was built for a 32-bit ELF target we cannot run the
memory address space tests as they all require ability to address more
RAM that can be represented on 32-bit.

We can't use a decorator to skip the tests as we need setUp() to run to
pick the QEMU binary, thus we must call a method at the start of each
test to check and skip it. The functional result is effectively the
same as using a decorator, just less pretty. This code will go away when
32-bit hosts are full dropped from QEMU.

The code allows any non-ELF target since all macOS versions supported
at 64-bit only and we already dropped support for 32-bit Windows.

tests/functional: Convert simple avocado tests into standalone python tests

These test are rather simple and don't need any modifications apart
from adjusting the "from avocado_qemu" line. To ease debugging, make
the files executable and add a shebang line and Python '__main__'
handling, too, so that these tests can now be run by executing them
directly.

tests/avocado: add test to exercise processor address space memory bound checks

QEMU has validations to make sure that a VM is not started with more memory
(static and hotpluggable memory) than what the guest processor can address
directly with its addressing bits. This change adds a test to make sure QEMU
fails to start with a specific error message when an attempt is made to
start a VM with more memory than what the processor can directly address.
The test also checks for passing cases when the address space of the processor
is capable of addressing all memory. Boundary cases are tested.
