Enable Dynamic partition [1/2]

* Disable system as root when dynamic partition is enabled
* Set the partition sizes
* Make the various partitions logical ones
* Label the physical partitions as system_block_device
* Introduce a binary to check post OTA status
* Use single fstab file for both system and recovery partitions.
