Remove port-specific test directories and excluded tests from
tinytest-codegen, and let it read said information from an external file.
This way tinytest-codegen is not limited to always generate tests for the
`qemu-arm` target.
This allows having port-specific test directory and excluded tests for more
than one QEMU bare-metal target.
The `qemu-arm` port Makefile was modified to work with the generator
changes and a tests profile file was added to said port.

- Split 'qemu-arm' from 'unix' for generating tests.
- Add frozen module to the qemu-arm test build.
- Add test that reproduces the requirement to half-word align native
function data.
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.
