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 2cf03ffa23 display: Replace hard-coded display with new config based display
Introduce a new config based system for specifying the on-screen
contents of an lcd screen.  The default screen configuration (found in
klippy/extras/display/display.cfg) is the same as the previous
hard-coded display, so this should not change behavior for existing
users.

Kevin O'Connor ef4710c6e0 hd44780: Increase timeout to 40us
There have been several reports that increasing the delay from 37us to
40us eliminates screen corruption on some clone hd44780 displays.
Increase the timeout value so that the standard code works on these
displays.

Kevin O'Connor 2e7f38eadd hd44780: Use two separate text framebuffers
There is concern that some lcd boards that emulate the hd44780 don't
support text updates that wrap the two text framebuffers.  Update the
code to treat the two text areas as two separate framebuffers.

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.
