Update api adapt esp core 3.0.0-alpha2

[lewisxhe]

esp32 core has been updated from IDF V4.x.x to IDF V5.x.x, and RadioLIb uses the updated API. The function has been tested normally in 3.0.0-alpha2,
Please see the specific changes esp32-hal-ledc.h

Guys, please, be aware that ESP_IDF_VERSION macro may not had been defined in Arduino Core 1.0.x series ( they use IDF < 4 )

@lyusupov thanks for pointing that out - in that case, I will add a check for defined(ESP_IDF_VERSION) to catch those version (although 2.0.0 was released more than two years ago at this point).

Great !

There was a breaking change between 1.x and 2.x that they had replaced LL hardware layer from (ESP32 only) custom design onto an API that supports other SoCs (-S2, -S3, -C3, ...)

My opinion that 1.0.x is still the best (stability and performance wise) provided that an application needs no compatibility with more recent SoCs.
