Updated Blinker class for compatibility with Arduino-ESP32 v2.0.1 

The update from Arduino-ESP32 2.0.0 to 2.0.1 contained significant changes to the structures used by the IDF for generic timers.  This broke the Blinker code (would not compile for ESP32-S2 and C3 chips).

The solution: Modified Blinker::isrTimer() to use a *generic* interrupt-clearing function when available (IDF version >= 4.0.0).  Below 4.0.0 the code continues to manually clear the interrupt flag by resetting specific structure variables, though the logic is simpler since this is only needed for the ESP32 chip (the S2 and C3 are not supported in earlier versions of Arduino-ESP32).

This provides for full compatibility with Arduino-ESP32 versions 2.0.1, 2.0.0, and 1.0.6.  The use of a generic interrupt clearing function when IDF>=4.0.0 will hopefully make this future-proof to any further changes by Espressif to the underlying timer structures.
