Damien George 31de44775c esp32: Add VFS FAT partition to partitions.csv and mount it as the FS.
This patch uses the newly-added esp32.Partition class to replace the
existing FlashBdev class.  Partition objects implement the block protocol
so can be directly mounted via uos.mount().  This has the following
benefits:

- allows the filesystem partition location and size to be specified in
  partitions.csv, and overridden by a particular board
- very easily allows to have multiple filesystems by simply adding extra
  entries to partitions.csv
- improves efficiency/speed of filesystem operations because the block
  device is implemented fully in C
- opens the possibility to have encrypted flash storage (since Partitions
  can be encrypted)

Note that this patch is fully backwards compatible: existing filesystems
remain untouched and work with this new code.
