Add InkHUD driver for WeAct Studio 1.54" display module (#7000)

* Strip redundant code from E-Ink driver

* Begin polling for E-Ink update completion sooner
In some cases, we might be waiting longer than we need to.

* E-Ink driver for WeAct 1.54" display
Currently identical to the popular GDEY0154D67 model. Kept separate now in case the drivers need to diverge in future.

* Put back code which sets the number of gate lines
