font-patcher: Add ScaleGlyph for Material Design Icons

[why]
Scaling the glyphs individually breaks a lot of glyph pairs or groups,
for example F0718-F071E.

[how]
Use one ScaleGlyph for the complete set. The set itself is already very
well scaled, i.e. all glyphs are maximized in a given design space and
that they look good next to pairing glyphs.
There is no need to use ScaleRules which is quite costly for such a big
range of glyphs (they all are copied twice in the process).
