add picker of available devices for andoid

[VysotskiVadim]

For now debugger support only one attached device, because it's default behavior of adb: if one attached device all commands directs to it.

adb is used inside Install msbuild task, and device id could be passed via parameter, don't remember exact names, but it is.
Debugger also use adb to setup port forwarding, stop and launch application.

Need to add ability to choose device where to install and debug application.

How it should looks like? It depends on technical ability,
The best option is to implement like in visual studio: picker with running devices.
If it not possible at least it could be done via text config with device id.
