debug: add run statusbar item

[vince-fugnitto]

What it does

Fixes: #5156

The following pull-request implements the select and run debug statusbar item:

• includes a new preference debug.showInStatusBar
• the statusbar item triggers the prefix select and run command
• the statusbar item reflects the current debug configuration, and updates when the config changes, and when the preference value is updated

How to test

Verify that the debug status bar item is updated accordingly based on the preference value, and the configuration updates:

1. start the application, and open the debug view
2. preferences:

• never: the debug status bar item is never displayed, if previously displayed it will be removed
• always: the debug status bar item is always displayed (on app start as well)
• onFirstSessionStart: the debug status bar item is displayed on a debug session is first started

3. verify that the debug status bar item is updated when a configuration is updated (label), and when the preference value is updated

---

Example: updating the configuration changes the label

Is it configurable in VS Code?

I was previously unaware of any configuration, but verifying I found the following preference which controls the behavior:

• VS Code Implementation

I have not tried, but code changes look good.

@vince-fugnitto could you assign someone to test it please?

[Anasshahidd21]

The changes work well for me.
I verified by running mocha test on theia workspace(the preference value was set to onFirstSessionStart).
Tested the value never and always.
The status bar correctly updates with the change in configuration.

LGTM
Works well
Could be in a separate PR: It would be nice to the end-user to know which value is the default value for any preferences when selecting it. In this case, by reading the code I can see it (default: 'onFirstSessionStart')

You can't always rely on the default preference value in the code, since the default can easily be overridden in the application's package.json.

Sounds like you're suggesting a potential Preferences widget improvement? However pretty orthogonal to this PR here, so if you care, you should open a separate issue about it, if none exist yet.

As a developper of Theia, I can open the file and see the default value. As a end-user, the only thing I see is in the preference setting while running Theia, I don't look inside the code to find the default value. I did an extra test and in VSCode, the default value is identified in the preference setting. If we try to align Theia with VSCode, then the default value is not identified

I don't know about the other preferences default setting, i was just looking at the preference setting for this issue.
