refactor: Improve type loading

- Don't include irrelevant types in the type loading process
- Ensure that modules from sap.ui.core are not looked up within the
linted project. This happened as there was no mapping for the
sap/ui/core namespace and TypeScript first tried to load the module
relative to the requesting module and only afterwards used the dts file
from "types".
