Marius Vikhammer cc9a929ea6 fix(esp_hw_support): clear LP core SW interrupt in wake stub before sleep 
When ulp_lp_core_wakeup_main_processor() is called, it sets the
PMU_SW_INT_RAW bit on the HP side. The normal sleep path clears this
bit before re-entering sleep, but esp_wake_stub_sleep() did not, leaving
the wakeup cause sticky. This caused the PMU to immediately re-trigger a
wakeup as soon as sleep was requested from the wake stub, producing a
rapid re-wakeup loop that eventually triggered LP_WDT_SYS resets.

Add a test case that verifies the wake stub can return to sleep correctly
across multiple LP core wakeup cycles without the re-wakeup bug.
