Include subdirectory URL fragment in the cache key

Use packaging.tags.Tag in place of Tuple This is the standard type used by packaging.tags. Making this change throughout the code lets us start switching over to using its tag-generating functions in get_supported(). We also get rid of a test, since it was superseded by `__str__` in packaging.tags.Tag.

Use legacy cache entries when they exist. Pip 20 changes the cache key format to include the interpreter name. To avoid invalidating all existing caches, we continue using existing cache entries that were computed with the legacy algorithm. This should not regress issue #3025 because wheel cached in such legacy entries should have the python implementation tag set.

Add WheelCache method to inform which cache was used Return whether the link was found in the persistent or ephemeral cache.
