telemetry: appcomposer_initializeProject metric #4280

Problem:
We're tracking resource counts in the App Composer console, but not in the VS
Code extension. This allows for tracking that telemetry event in VSC as well.

Solution:
This adds the `appcomposer_initializeProject` telemetry event, which records the
`resourceCounts` and `totalResourceCount` values coming from `FigAssets`.
