feat(vscode): support for disabling typescript plugin

[johnsoncodehk]

Changes

When Hybrid Mode is explicitly or automatically disabled, @vue/typescript-plugin will no longer be effective by default to avoid potential crashes of tsserver.

A new option "vue.server.hybridMode": "typeScriptPluginOnly" is introduced, to address which allows users to still enable @vue/typescript-plugin when Hybrid Mode is disabled.

For explanations of all states, please refer to:
