QWIIC OLED optimization (size reduction and speed improvements) and added new font option

[infinityis]

Description

Resolved "TODOs" for optimizing horizontal and vertical line drawing. New implementation reduces compiled code size by approximately 60 bytes for applications drawing both horizontal and vertical lines. Execution speed is also improved by eliminating multiplication from loops and drawing vertical up to lines 8 pixels at a time.

Added a third font (font5x7lite) which is a subset of the existing 5x7 font. It includes the same character subset as the 8x16 font which is mostly the alphanumerics and common symbols. If this font subset is used in lieu of the complete 5x7 font, the compiled file size decreases by almost 800 bytes.

Compiled file size reductions were measured for Atmega32u4 as a target.

Just a heads up, unfortunately this is pretty much the opposite direction that we're headed.

#14174

Specifically, we're trying to consolidate the drivers and then move to Quantum Painter for a much more unified interface/api.
