esp32: add support for ESP-IDF v5.5 #140

This PR improves the newly merged ESP32 support from #139 by adding compatibility for the newer ESP-IDF v5.x. The version now in master uses the older variants of the LEDC APIs, which received incompatible changes as described in the Arduino ESP32 project's 2.x-to-3.0 migration guide.

These changes aim to provide compatibility with both versions of arduino-esp32, though I have only tested them with the newer version.

After reviewing this PR again today, I noticed a minor simplification to my original changes. Pushed separately for review, but I would be happy to see it squashed it into the previous commit before merging.

Pushed another fix that probably would cause a minor regression with 4.x.

That said, I doubt anyone actually detaches servos in practice, as repeated attach/detach cycles will quickly exhaust the available slots. Fixing that remains an open problem for another PR and probably deserves to be solved by factoring the solution into common code that could be used by other chips that use the same allocation strategy. Other sections of the code offer similar opportunities for re-use, so I personally don' t want to start tugging on that thread....
