esp_flash: fix the coredump issue

Browse Source 
During coredump, dangerous-area-checking should be disabled, and cache
disabling should be replaced by a safer version.

Dangerous-area-checking used to be in the HAL, but it seems to be more
fit to os functions. So it's moved to os functions. Interfaces are
provided to switch between os functions during coredump.
