refactor(linter): introduce ContextSubHost for cross script block analyse

[Sysix]

Another approach to #12541 stack.
Because vue/valid-define-emit and other rules required the semantics of the other script block.

The Goal:

Linter.run should run with the complete file context. In vue files and others, there can be multiple Semantics / Module Records.
Because vue requires some magic compiler rules, the linter should have access to the complete file.
This will also fix the offset bug in #12758. Don't merge both stacks without rebasing.

I do not like the loop part. Maybe you guys have some better ideas.

Pull Request Overview

This PR refactors the linter architecture to support multi-script block analysis by introducing ContextSubHost. This enables proper linting of Vue files and other frameworks that contain multiple script blocks within a single file, such as <script> and <script setup> tags in Vue components.

• Introduces ContextSubHost to handle individual script blocks within a file
• Modifies ContextHost to contain multiple ContextSubHost instances and iterate through them
• Adds framework-specific options to support Vue setup script detection
