* Always filter out the variant name attribute: it is never requested
by consumers, while its presence makes Gradle count it as an
unmatched attribute, sometimes leading to ambiguity;
* Filter out the build type attribute: if all variants have the same
build type, then remove the build type attribute from all variants;
Otherwise, remove the build type attribute from the release variants
in order to make them compatible with all other consumer's build
types.
* Add an opt-out flat for always keeping the attribute:
"kotlin.android.buildTypeAttribute.keep" Gradle property
