19487: nanocoap: implement extended tokens (RFC 8974) r=benpicco a=benpicco
19781: cpu/nrf{53,9160}: add pwm support r=benpicco a=dylad
### Contribution description
This PR moves the nRF52 PWM driver to `cpu/nrf5x_common` to allow nRF9160 and nRF53 to use this driver.
IP is identical on these families.
I didn't test on nRF9160DK and I didn't test if there is any regression on nRF52-based board as I don't have any so tests are welcome !
However it works fine on nRF53-based board.
### Testing procedure
Flash the `tests/periph/pwm` test application on `nrf5340dk` or `nrf9160dk`.
You can then use the `osci` command to make the onboard LEDs "breath".
You can also attach an oscilloscope and/or logic analyzer to watch the signal.

Contribution description
RFC8974 allows for token length of up to 65804 Byte in order to store Client state in the token.
This is easy to implement in nanoCoAP, so let's give it a try.
Testing procedure
Currently no use case is associated with this, but I extended the unit test.
Maybe we should only enable this when a pseudo-module
nanocoap_token_extis used.Issues/PRs references
