Light up python profiling in the VS Performance Profiler

[AdamYoblick]

Notes from the VS team:

Here is some info on how to show up in the Performance Profiler (Alt+F2) UI.

Grab our SDK package (Package Details - Azure Artifacts (visualstudio.com)) then export an ITargetProvider.

This package will need to be added as a build dependency in our packages.config. Adam will handle this in a previous task.

ITargetProvider: Anything that implements this interface shows up in that “select target” dropdown.

ProcessTargetProvider.cs - Repos (visualstudio.com)  This is the one for our attach to process selection
DockerTargetProvider.cs - Repos (visualstudio.com)
RunningWindowsStoreAppTargetProvider.cs - Repos (visualstudio.com)
WindowsStoreAppTargetProvider.cs - Repos (visualstudio.com)
The main method where the action happens is GetTargetsAsync which returns the ITarget that the profiler uses.
