Glossary changes not reflected in machinery results

[nijel]

Describe the issue

The machinery caching does not include glossary state for backends utilizing it. That can lead to showing outdated results in automatic suggestions.

I already tried

• I've read and searched the documentation.
• I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

1. Install machinery service supporting glossaries.
2. Create a glossary entry for a term used in a string
3. View automatic suggestions on that string
4. Change the glossary term
5. View automatic suggestions on that string again

Expected behavior

The automatic suggestion should reflect glossary changes.

Additional context

get_cache_key for GlossaryMachineTranslationMixin should include a glossary checksum, most likely logic from get_glossary_id should be extracted and reused here.
