No longer publicly expose the PeripheralClockControl struct (#817)
* No longer publicly expose the `PeripheralClockControl` struct

* Update examples as needed to get things building again

* Update CHANGELOG.md

* Address review feedback, fix a warning

* Use a critical section for all devices other than the ESP32-C6/H2, as they modify multiple registers

* Rebase and update `etm` driver to fix build errors
