19939: boards/stm32f723e-disco: enable ST7789 display r=benpicco a=gschorcht

### Contribution description

This PR enables the ST7789 display and the touch panel for the `stm32f723e-disco`.

The PR requires PR #19937.

### Testing procedure

```
BOARD=sstm32f723e-disco make -j8 -C tests/drivers/st77xx
```
should work.

### Issues/PRs references

Depends on PR #19937
