Handle resolution watching when its dynamic scriptInfo

[sheetalkamat]

1. Dont watch failed lookups or affected files location in dynamic script
2. Dont watch typeRoots if its the inferred root that is using server's current directory (which is lib file location and used if projectRootPath is not sepcified) as current directory or current directory is not watchable. (Sometimes chat blocks are created with projectRootPath as "/")
3. Dont watch typing installers found location for same criteria

Fixes #62887

Pull request overview

This PR addresses issue #62887 by preventing unnecessary file watchers from being created for dynamic script infos (e.g., chat blocks, untitled files). Dynamic scripts are identified by paths starting with ^ and don't correspond to actual filesystem locations, so watching their resolution paths, type roots, and typing installer locations is unnecessary and can cause issues.

Key Changes:

• Skip watching failed lookups and affected file locations for dynamic scripts
• Skip watching type roots when inferred project's current directory is the server's current directory (lib location) or not watchable (e.g., projectRootPath="/")
• Skip watching typing installer locations under the same criteria
