KonstantinKondrashov b902d6be39 esp32: Switch SPIRAM stack in esp_restart_noos() to internal stack
If esp_restart_noos() is run and the stack address points to external memory (SPIRAM)
then Cache_Read_Disable() raises up the error "Cache disabled but cached memory region accessed"
to fix this we switch stack to internal RAM before disable cache.

Added unit tests.
