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.

Relevant code

Only chrome supports Bluetooth according to canIuse.

Maybe I suggest that the gio-plugins be looked at for this. It has all these extra things that are often needed to access native OS features.

https://github.com/gioui-plugins/gio-plugins

they can be used independently of gio btw. There is some amazingly good stuff there and on the roadmap

[kkoreilly]

I am definitely interested in supporting all of those things, but it does not seem like the plugins can be used without importing gio, which is not something that we are going to do. However, I am absolutely willing to consider copying relevant code into Cogent Core to support all of those features. My priority right now is getting the core framework ready for an initial release, but after that, I will have more time to work on implementing more features like these. PRs are always welcome.
