tests: For pyboard, add test for I2C error handling and recovery.

# test I2C errors, with polling (disabled irqs) and DMA
import pyb
from pyb import I2C
tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.

stm32: Replace master/slave with controller/peripheral in I2C and SPI. Replace "master" with "controller" and "slave" with "peripheral" in comments, errors, and debug messages. Add CONTROLLER and PERIPHERAL constants to pyb.SPI and pyb.I2C classes; retain MASTER and SLAVE constants for backward compatiblity.
