Add xterm as an IDE

[filiptronicek]

Description

Adds Xterm.js as a web alternative to connecting to your workspace via SSH from your terminal. The code can be found at https://github.com/gitpod-io/xterm-web-ide and the Docker image is at ide/xterm-web.

Note: The original PR is at #8464, but it was merged incorrectly.

Note: this relies on #16847 being merged first

How to test

1. Open the preview environment
2. In the preferences, select notice there is no Xterm IDE
3. In Configcat, include yourself in the enable-rule for experimentalIdes (non-prod)
4. Wait a couple of minutes (🫖 time)
5. Reload and see the Terminal IDE magically appear
6. Create a workspace and have a blast

Useful commands

Re-pull the IDE:

kubectl rollout restart deployment/ide-service

AI-Generated Pull Request Summary: This pull request introduces changes related to adding an experimental "Terminal" IDE option. The main additions are:

1. A new experimentalIdes feature flag added in the FeatureFlagContext.
2. The IDEOption interface now has an experimental field to mark IDE options as experimental.
3. A new function filteredIdeOptions() is implemented to filter IDE options based on the experimentalIdes flag.
4. The Terminal IDE logo SVG file is added.
5. IDE configuration updates to include the new Terminal IDE option with the experimental flag set to true.

Additionally, there is a minor change in the loading frame, where the frame is now prepended to the body instead of being appended.
