Enhancement: Ability to select multiple media files inside Media view

[polynook]

Is your feature request related to a problem? Please describe.
I often need to delete more than one media file based on filtered name. As it stands today, I need to delete media files one by one. It would be nice to have an ability to select more than one media file and delete the entire selection.

This could further be extended to affect media scripts, as of now they seem to be able to be executed either on a single media file, or on the entire folder. Having an ability to execute them on a custom selection would be useful.

Describe alternatives you've considered
Alternative is to manipulate files via the OS's file system or inside VSCode's file browser but that's less convenient.

A new command bar got introduced which allows you to perform actions on the selected items.
