component-type-helpers: Remove side effects

[vikingair]

This would allow bundlers to tree shake the module code when imports are not done via import type.

E.g.,

import { ComponentProps } from 'vue-component-type-helpers';

Also, I would like to know why the code needs to be default exported as a string containing the same TS code again. Is it maybe some artifact from the past and or only relevant to Vue2?
