Make Context Menu Buttons to work with multiple files

[AllanOricil]

Is your feature request related to a problem? Please describe.
When we click with the right mOuse button on a Metadata file, a few buttons appear, like "SFDX: Deploy to Org". These buttons only work with one file at a time. Even when you select multiple files and click on the button, only the last one you selected is deployed.

Describe the solution you'd like
Context Menu buttons should work with multiple files.

Describe alternatives you've considered
I have to deploy one file after another. It requires multiple mouse clicks

Additional context
N/A
