Add support to open Boundary Desktop targets with App Links/URIs

[manoelhc]

Is your feature request related to a problem? Please describe.
Not into a problem but it would be easier to write documentations or explain to the user how to get to the target.

Describe the solution you'd like
Add support to connect to a target by using URIs, for instance: boundary-ui://o_CVhEdpFI9t/ttcp_rJUKbtbqfE, so it would open Boundary in the proper target page with the connection details.

Describe alternatives you've considered
Not sure if there's a proper alternative to this.
