Angus Gratton 3ec8b9a77c all: Replace legacy name with MicroPython and MPy as applicable.
With the aim of getting consistency, and removing the need to learn an
additional term, replace uses of uPy/uPython with MPy/MicroPython.

Rule of thumb was to use "MPy" abbreviation where "CPy" is used nearby, but
the full word MicroPython otherwise.

This work was funded through GitHub Sponsors.
