u_boot_pylib: tout: Add newline parameter to output functions

Add a newline parameter to all output functions (info, error, warning,
notice, detail, debug, user_output, do_output) to allow suppressing the
trailing newline. This is useful for progress output where multiple
calls should appear on the same line.

Example:
    tout.info('Processing...', newline=False)
    tout.info('done')

Also fix typos in docstrings (msg; -> msg:).
