Support more native features such as bluetooth

[kkoreilly]

Describe the feature

We should support more native features such as bluetooth. This is related to #712.

See https://github.com/fyne-io/fyne-x/pull/58/files and https://git.wow.st/gmp/ble/src/branch/master/BlessedConnect.java (from @MatejMagat305 in #981).

This is not super urgent, but once we have released v1 and everything is stable, it would definitely be nice to add.
