fix(typescript-estree): pass extraFileExtensions to projectService

[alfredringstad]

PR Checklist

• Addresses an existing open issue: fixes Bug: EXPERIMENTAL_useProjectService does not respect extraFileExtensions #8899
• That issue was marked as accepting prs
• Steps in Contributing were taken

Overview

Uses setHostConfiguration to pass extraFileExtensions to project service, when using EXPERIMENTAL_useProjectService. This fixes an issue where project service would not detect the appropriate tsconfig file when using non-default file extensions.

The tests are checking that the configFilePath is set in the compiler options. If it's not, it's an indication that the default inferred project is used. I duplicated the test cases used for the non-experimental projects option.
