[JetBrains EAP] Port Forwarding improvements

[felladrin]

Description

This PR brings the following changes:

• We now rely on PerClientPortForwardingService for controlling all Ports (Forwarded + Exposed) in JetBrains Client. For this reason, GitpodPortsService was removed.
• GitpodCLIService.kt and GitpodClientProjectSessionTracker.kt were updated because they relied on GitpodPortsService.
• Whenever Supervisor informs the client there was a change in the Name, Description, Visibility, Served or Exposed status of a port, Ports View is updated accordingly.
• GitpodPortForwardingService became an interface, which is implemented only by the Latest package. It's not available for Stable.
• extractLocalHostUriMetaDataForPortMapping moved to an object (LocalHostUri) as it's a pure function with its test suit. Leaving it inside a Service would make it hard to instantiate and test.
• GitpodGlobalPortForwardingService was removed as we shouldn't use JetBrains' GlobalPortForwardingService. This is intended for plugins running in local mode instead of remote.

This is how the Ports View currently looks like:

Notes:

• By default, when trying to forward a port which is already in use on Client, a random port will be forwarded (and we take it into account when fetching the forwarded port on client).
  
  
• GitpodPortForwardingService is only available when using Latest (EAP) IDEs, that's why we use serviceOrNull<GitpodPortForwardingService>() when fetching that service.
• Currently, there's no way to sort the ports in Ports View. They appear in the same order they're registered.

How to test

1. Open the Preview Environment of this PR and start any workspace using EAP IntelliJ IDEA.

• Run python -m http.server 3000 and confirm that:
  • a notification is displayed informing that the port is available. Then click "Open browser" and confirm it opens http://127.0.0.1:3000.
  • port 3000 is displayed on the Ports View twice: one with the forwarded address and another with the exposed URL.
  • Copy Web URL and Copy URL dropdown options are working:
    • 
    • 
• In another terminal run gp ports visibility 3000:public and confirm if in Ports View the Exposed Port doesn't have the lock icon anymore.

2. Open the Preview Environment of this PR and start any workspace using Stable IntelliJ IDEA.

• Run python -m http.server 3000 and confirm that a notification appears with a link to "Open browser". Click the link and check if it opens a Gitpod URL, as there's no port forwarding in the Stable version.

I am reviewing this now 👀

I've started reviewing but not finished writing my feedback, I need some more time 🙏

[andreafalzetti]

I'd suggest to hold it / move to draft while we understand more about the "default lock icon".

Icons updated:

But it's important to mention that this PR is not about the Ports View, it's about avoiding querying the Supervisor about the status of the ports by syncing the state with the PerClientPortForwardingManager of JetBrains and querying it instead.

Good idea decoupling the icons not to hold the PR 🙏

Code changes LGTM, tested and works as expected 🙏

Nice clean up and improvement 🚀
