Support multiple <application> or <uses-sdk> elements in manifest_*.py
Manifests may now have multiple copies of elements if they are
disambiguated with android:featureFlag attributes. Remove the
restrictions on duplicate elements from manifest_check.py and
manifest_fixer.py, and instead iterate over all matching elements.
Test: manifest_check_test.py, manifest_fixer_test.py
