Add SH1107 for 128x64/32 OLED featherwings

[tyeth]

This ties in with adafruit/Wippersnapper_Components#263

The build task was modified to allow single board builds, due to circuitpython hogging the build agents.

The SH1107 is added, for the featherwing. It uses the width as height and height as width in the learn guide example, then relying on rotation = 1. I've had to include this to make the board usable in the interface, but it now begs the question of whether we add rotation to the protobuf, and as a degrees decimal, or possibly just 0-3.

Multiple SSD1306 options are added to support extra displays/components, and the library args to no longer call i2c begin.

@brentru this is ready for review

Is this happening currently? Will this stop happening in a few hours? Days? I don't want to modify the build script to get something passing immediately.

No, it is an optional box when the job is used via workflow dispatch manually from the actions page. It does the same behaviour as before.

If you goto that page, the CI job, then choose branch sh1107, you see the extra box

@tyeth I'm requesting some changes as it's the first PR you've done against the displays. I also have some questions

@brentru this should be good now. The components PR is updated too: adafruit/Wippersnapper_Components#263

LGTM - thank you for making the requested changes.
