fix(linter/plugins)!: prevent access to cwd in createOnce

[overlookmotel]

Supporting JS plugins in LSP requires that different workspaces have a different value for Context#cwd.

As a first step, prevent accessing cwd property, or calling getCwd method in createOnce. Later on, we can make cwd a dynamic property.

Pull request overview

This pull request prevents access to the cwd (current working directory) property and getCwd() method within the createOnce context of JS plugins. This is a breaking change that prepares for supporting different workspaces with different cwd values in the LSP (Language Server Protocol) implementation.

Changes:

• Modified cwd and getCwd() to throw errors when accessed in createOnce context instead of returning the current working directory
• Updated tests to verify that accessing cwd/getCwd() in createOnce now throws appropriate error messages
• Removed the cached cwd variable from the ESLint compatibility layer since it's no longer accessible in createOnce
