feat: Add aep.api.resource annotation for resources

Similar to google.api.resource, this commit introduces a new proto annotation for AEP resources. This allows for the extension of new metadata as needed.

The annotation includes the following fields:
- plural
- singular
- type
- patterns
- parent
