Tests framebuf1 and framebuf2 do not take the need for byte-aligned
strides into consideration when calculating buffer lengths.
Accordingly, the buffers allocated are slightly too small. Fixed
buffer length calculations.

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.
