RTC timer HAL tests

This test app validates the esp_hal_rtc_timer component directly.

It focuses on:

1. Reading RTC timer counters.
2. Converting RTC slow-clock ticks into elapsed time and checking the result against a measured delay.
3. Exercising alarm interrupt raise/clear behavior on targets with the newer multi-target RTC timer hardware.
