platformio.ini: add m5stack-timer-cam

Add the m5stack-timer-cam definitions following information from the
board documentation [1] and the board entry on platform.io [2]. Tweak
the upload speed to use a known working value. Mention the X version in
the readme as well since it uses the same board and is just a chassis
change.
