I believe this could be defined in https://github.com/vuejs/language-tools/blob/master/packages/vue-language-core/src/utils/globalTypes.ts since it doesn't depend on any dynamic code.
(I'm not super familiar with this project so you might wait for confirmation on that)

This fixes vuejs/core#9381
Like the fix in vue/core vuejs/core#9336 we use an alternative Omit that doesn't break discriminated unions in props. More information can be found here: microsoft/TypeScript#31501
