This commit allows you to pass an exception object in as the exc_info kwarg
(CPython allows this), so logging exceptions can work even if the
MICROPY_PY_SYS_EXC_INFO option is disabled in the firmware.
Separately to that, currently even when sys.exc_info() is enabled, it's
only printing the traceback to _stream = sys.stderr - not to the configured
logging handlers. This means for instance if you've got a file log
handler it misses out on the tracebacks. That's also fixed in this commit.

Previously a child logger just uses the global default when unset.
Modified to matches the CPython behavior of using the parent's level.
Also implemented CPython's getEffectiveLevel() which provides a convenient
way to implement this. In our version, we only ever have one parent
(the root), so it only has to recurse one level.
Also set the default level to WARNING to match CPython.
Updated the examples to highlight the differences (but they now match).

Add support for all format specifiers, support for `datefmt` using
(optional) strftime, and support for Stream and File handlers.
Ports/boards that need to use `FileHandlers` should enable
`MICROPY_PY_SYS_ATEXIT`, and enabled `MICROPY_PY_SYS_EXC_INFO` if using
`logging.exception()`.
