Merge remote-tracking branch 'origin/bladerf_testing' into integration_2026_w07 (!3894)

Reimplement BladeRF radio driver, make it work for 5G

This MR reimplements the BladeRF radio driver such that it is usable for
5G. On the way, we remove unused code, refactor it for readability, and
update configuration.

Tested:

- 40MHz carrier as gNB
- 20MHz carries as gNB

An initial focus was 2x2, but I did not manage to do this yet.
Documentation on the format is here [1] and there is a helper [2]. I
will do this later.
