cmd: part: support lookup by UUID

The 'part' command currently allows looking up a partition only by its
number or name.

Extend the 'number', 'start', and 'size' subcommands to support looking
up the partition via its UUID. Unlike names, UUIDs guarantee unique
partition identification, avoiding ambiguity.

The logic is updated to check if the provided string is a valid UUID
before falling back to a name-based search. The help strings for these
subcommands are updated accordingly.
