extension-api: adds enablement in contributed commands

[benoitf]

Is your enhancement related to a problem? Please describe

Sometimes we don't want to have a command being enabled

For example if we're not matching all required conditions, commands should not be available.

Describe the solution you'd like

Adds enablement as a command contribution

  "contributes": {
    "commands": [
      {
        "command": "my.command",
        "title": "My Command",
        "enablement": "view == myViewsExplorerID"
      },

enablement is a when-clause where we can have access to Podman Desktop current contexts objects (like the current view, etc) or some custom context

to register a custom context, extension should call something like

podmanDesktopAPI.commands.executeCommand('setContext', 'myExtension.showMyCommand', true);

enablement would be then

 "enablement": "myExtension.showMyCommand"

note: enablement on commands should also work on contributed views with a when clause
