Florian Heilmann 3dcac1308e display: Move glyph definition to printer config
This commit allows to modify the icons (or glyphs) in the displays that
support it. Existing icons can be modified and new icons can be added via
a [display_glyph] section in the config.

Kevin O'Connor 97927172f1 st7920: Use display xor capability when animating glyphs
Use the xor capability of the display to animate the glyphs, which
reduces the number of glyphs needed from 4 to 2.  This should make it
easier to add future animations if desired.

Suggested by @marcio-ao.

Kevin O'Connor 30013a1fb8 mcu: Rename add_config_object() to register_config_callback()
Change the name of the config registration method and pass an explicit
reference to the callback to the new method.  This makes the
relationship between mcu registration and build_config() more clear in
the calling code.

Kevin O'Connor 273a98d39a pins: Explicitly pass can_invert and can_pullup to lookup_pin()
Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin().  This simplifies the code for the
cases where it is not valid to invert or pullup.

Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.
