For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.
This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c. Enabling MICROPY_PY_MACHINE will include this
module.
As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

Adds support for 3 Cortex-M boards, selectable via "BOARD" in the Makefile:
- microbit, Cortex-M0 via nRF51822
- netduino2, Cortex-M3 via STM32F205
- mps2-an385, Cortex-M3 via FPGA
netduino2 is the default board because it's supported by older qemu
versions (down to at least 2.5.0).
The way tinytest was used in qemu-arm test target is that it didn't test
much. MicroPython tests are based on matching the test output against
reference output, but qemu-arm's implementation didn't do that, it
effectively tested just that there was no exception during test
execution. "upytesthelper" wrapper was introduce to fix it, so switch
test implementation to use it.
This requires passing different CFLAGS when building the firmware, so
split out test-related parts to Makefile.test.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
