shell: Improve device list command with an optional filter

It might come in handy to filter the output of a device list
command, by adding a filter (auto-completion enabled as well).

Such as:
$ device list uart
devices:
- uart@2f8 (READY)
  DT node labels: uart1
- uart@3f8 (READY)
  DT node labels: uart0
