bug: Relative imports of Prop/Event types from abstract component cannot be resolved in components.d.ts for subclasses

[FabioGimmillaro]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Stencil Version

4.43.4

Current Behavior

When an abstract component uses imported types for Events/Props/Methods, the components.d.ts might have an error referencing said types.

Expected Behavior

When generating the components.d.ts the correct relative imports should be generated dependent on the abstract component which imports the types.
