Fix aliases for users of label-keyed string dicts.

Aliases mess with the assumption that

    attributeValue.containsKey(target.getLabel())

for every target in the prerequisites of a LABEL_KEYED_STRING_DICT
attribute.

The solution is to use AliasProvider.getDependencyLabel(target) instead.
This fixes it for all current users, including SkylarkRuleContext.
This also adjusts config_setting flag_values and Android feature_flags
to do intelligent things with aliases in their respective attributes.

RELNOTES: None.
