Add SPRO-SPRACINGH7NANO.config

[theojalba]

Add back SPRACING H7NANO board which was removed in Betaflight 4.4.

The starting point for this configuration is the existing SPRACING H7EXTREME config in BF 4.4, and I applied hardware changes based on the previous H7NANO config in BF 4.3.

These are the changes for the 4.4-maintenance branch.

There are 2 additional pull requests:

I tested this branch locally by adding the options below into common_pre.h. I confirmed that all the components on my build (CRSF Nano, Vista, GPS, motors) are working. I also did a quick indoors hover test.

Reflashed, retested, passed. 🎉

@hydra: As requested, here are the resource show, timer show, dma show, dump and diff outputs for this build post flashing. With 4.4 after flashing the board starts beeping. These are the outputs in that beeping state.

Will skip adding this config to 4.4-maintenance.
