Nucleo f429 zi new graphic display capsule

[CristianSLazar]

Pull Request Overview

Add a new graphic display capsule for the board Nucleo-F429ZI (and it's dependencies), which fixes a bug that caused the first column of pixels on the board display to be dead. The implementation is unfinished due to a bug with the boards/components/src/bus.rs i2c_master_bus_component_static! macro (opened separate pull request; waiting for review).

Testing Strategy

This pull request is untested since it is unfinished.

TODO or Help Wanted

This pull request still needs:

• Modifying/utilizing the existing screen.rs capsule with it's components instead of a separate graphics_display.rs capsule.
• Initialization of the graphic display capsule's i2c bus.
• Update documentation.
• Remove commented code and test implementation.

Documentation Updated

-[ ] None.

Formatting

• Ran make prepush.
