Add supports_consolidated_metadata to ManifestStore

[jsignell]

I was just experimenting with using ManifestStores directly and got tired of typing consolidated=False.

• Closes #xxxx
• Tests added
• Tests passing
• Full type hint coverage
• Changes are documented in docs/releases.rst
• New functions/methods are listed in api.rst
• New functionality has documentation

FYI @jsignell, #827 also removes the need to explicitly set consolidated=False. I'd still definitely support using this approach if you're interested in continuing with the PR. Just ping if/when you'd like a review.
