Summary

This PR intends to add a new ioctl command to the MTD subsystem named MTDIOC_ERASESTATE for retrieving the byte value of an erased cell of the underlying memory device.

Also implemented the handling of the MTDIOC_ERASESTATE command for those drivers that already provide the byte value for their erase states.

Impact

New ioctl command to the MTD API.

Testing

Tested using esp32-wrover-kit.
