Volar hybrid mode compatibility with typescript-svelte-plugin

[jasonlyu123]

Describe the bug

Thread for tracking Volar hybrid mode compatibility issues. Documenting some issues currently found and continuing the conversation of microsoft/TypeScript#57630.

1. Typescript plugin is enabled in all projects without a tsconfig/jsconfig.json
2. The plugin is enabled by default. The config request to disable it only happens when a ts/js file is opened. So the "svelte.enable-ts-plugin": false config doesn't do anything until a ts/js file is opened.
3. Debug.assert in ts 5.5 nightly: https://github.com/microsoft/TypeScript/blob/353ccb7688351ae33ccf6e0acb913aa30621eaf4/src/server/project.ts#L1160. Doesn't seem to happen when opening a svelte project.

For 2, we might need to disable the ts plugin when the config is { global: true, ... } and enable it when the config request we sent arrives.

Probably Volar problems:

1. Debug.assert in ts 5.3: https://github.com/microsoft/TypeScript/blob/63717cf44a64585175c76c336c8f8d87d5384d16/src/server/project.ts#L1518. This is because vue typescript plugin patched getScriptVersion to be a compound version id but TypeScript expect update should only happen through Project.updateGraph. Might need to check if this only happens if the Svelte extension is enabled.

@johnsoncodehk, Also, I can't reliably reproduce the problem reported in microsoft/TypeScript#57630. Can you provide a more detailed step?
