Python API to get tag counts, ignore deleted/disabled ObjectTags by default [FC-0036]

[bradenmacdonald]

This PR:

1. Makes the get_object_tag_counts API available via python as well as REST. Previously it was REST-only.
2. Makes the get_object_tags and get_object_tag_counts APIs ignore tags from deleted or disabled taxonomies by default. Anything else would be confusing for users. Keep in mind, we do preserve the underlying ObjectTag data; we just don't want to display it.

This is for openedx/modular-learning#118 part 1b.

Private ref: FAL-3564.

FYI @ChrisChV since you mentioned the issue with deleted/disabled object tags being included in the APIs - I fixed it here.

👍 Looks fine, thanks @bradenmacdonald !

But I think this needs a version bump?

• I tested this using django runserver, hit the modified APIs
• I read through the code
• I checked for accessibility issues N/A
• Includes documentation
• User-facing strings are extracted for translation N/A
