Provide a way of accessing metadata dependencies

[laszlo-foldi-attentioncrm]

Is your feature request related to a problem? Please describe.
My pain point is, when developing portable solutions I'm always struggling with finding dependencies for my classes. For example, I have a base package for our company containing basic trigger framework, logging framework, rest framework, but when from this multi package project I only want to deploy a single package, I'm always struggling with properly extending the package xml related to said package.

Describe the solution you'd like
I'd like to have a way to show dependencies for either a full package directory or a package xml. This feature already exists when creating packages from the UI and I can fetch dependencies for a single class using the 'Show Dependencies' button, but I'd like to have a similar feature in the VSCode extension.

Describe alternatives you've considered
The only alternative solution I've found is, creating a package from the UI as it'll fetch all my dependencies for me. However, that's less usable in my context as I don't want to create actual packages just to manually copy all dependencies to a package xml file.
