Change write_graphics() from taking one pixel row of n characters to
taking all the rows and columns for one character cell.

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.

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.

Add write_glyph() support to hd44780.py. Update uc1701.py and
st7920.py to support writing single character glyphs via
write_glyph().

Move the st7920 icon rendering optimizations from display.py to
st7920.py. This simplifies the code for other displays.

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.

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.
