feat(lsp): Removes built-in LSP configuration options and improves configuration loading mechanism

- remove configuration options such as lsp.enabled, lsp.allowed, lsp.excluded, etc. from settings.json schema
- Delete lspSettingsSchema.ts files and associated JSON schema definitions
- Removed VS Code settings loading function, no longer merge. vscode/settings.json configuration
- Updated LSP documentation to reflect new configurations and experimental flags
-remove allow/exclude parameters in NativeLspService constructor
- Create new LspConfigLoader classes to handle LSP configuration loading and merging
- Updated debug guide to match the new configuration mechanism
- Simplify loadCliConfig functions, remove startLsp options
- Reconstruct the configuration loading process to remove duplicate configuration merge logic
- Add LspConfigLoader classes to implement configuration parsing and merging functions
