That's because facemenu-set-face's argument should be a symbol, not a
string:

   (facemenu-set-face 'highlight)

> so why is the key sequence \M-gy bound to facemenu-add-new-face

It's not; it's just that facemenu-set-face called
facemenu-add-new-face, and the latter barfed because its argument was
not a symbol.

Because the face information isn't written to the file.

It changes the buffer, not the file.

Use Enriched Text mode ("M-x enriched-text-mode RET").
