Link to issue number:

None. Removes code marked as deprecated in #12753

Summary of the issue:

As part of #12753 various constants in languageHandler were moved into an enum but kept at the module level for backwards compatibility. Since NVDA 2022.1 is a backwards compatibility breaking release it makes sense to remove them.

Description of how this pull request fixes the issue:

Deprecated constants are removed.

Testing strategy:

Made sure that removed constants are not used directly in the code.

Known issues with pull request:

None known
