fix: Yarn doesn't want to Link Firebase

[askadityapandey]

What's the problem this PR addresses?

This Pull Request addresses the issue where Yarn fails to link packages due to path length limitations on Windows. Specifically, it resolves the problem where certain subcomponents of Firebase do not get linked properly.

fixes #6512.

How did you fix it?

1. Import constants from @yarnpkg/fslib:

   • This module provides constants like MAX_PATH, which is used to determine the maximum path length on Windows.

2. Add Windows-specific path handling:

   • In the processWorkspace function, the code checks if the platform is Windows (process.platform === 'win32').
   • It then converts the portable path to a Windows path using npath.fromPortablePath.
   • If the path length exceeds constants.MAX_PATH, it attempts to shorten the path for virtual packages.
   • If the path is still too long, it uses the extended-length path syntax (\\?\) to handle long paths.

3. Report linked packages:

   • The reportFooter function is added to the project.installWithNewReport call to provide a summary of the linked packages.
