[Permissions Policy] Rename remaining 'FeaturePolicy' terms

This CL renames remaining 'FeaturePolicy' occurrences in
method names, class names and test names.

Note: 'FeaturePolicy' in feature enums
(web_feature, base::features, etc.) are not renamed, but
future usage of 'FeaturePolicy' in those enums should be discouraged.
