8c307a5720 sleep: fix deadlock in esp_timer_impl_advance after light sleep
When light sleep is started, the other CPU gets halted using DPORT
stall mechanism. This can happen while it is inside an esp_timer
critical section, which may lead to a deadlock. This change adds
functions to take and release esp_timer lock before entering
DPORT critical section, preventing the deadlock.

2d90da0817 esp32: Deactivate wakeup trigger after first wakeup
The timer wakeup function once activated cannot be disabled later using existing api. If user wants to use different wakeup sources after first sleep but it does not work. This change disables timer wakeup trigger in configuration that will be set into appropriate RTC registers in esp_light_sleep_start() function.

Added function esp_sleep_disable_wakeup_source() to deactivate wakeup trigger for selected source.
Updated documentation for this function in sleep_modes.rst file to pass make html.
Updated unit test to check this functionality for light sleep.
The test_sleep.c unit test is updated to add reliability for auto unit testing.

f31efb697c newlib: rename esp_setup_time_syscalls to esp_set_time_from_rtc
This function no longer sets up syscalls, and new name reflects its
purpose better.
