Remove framework-connectivity-annotations library

This library can be removed because the annotations are no longer
used out of module.

@RestrictBackgroundStatus and @MultipathPreference are defined
in connectivity mainline module. Annotate these in non-updatable
platform is not going to be manageable long term. For example,
if the module gets updated and the annotation gets more values
then it's a problem in non-updatable platform. So, it should
not have IntDef cross module boundaries.

Ignore-AOSP-First: AOSP doesn't include this change yet
Bug: 183972925
Test: build
