Add offline support to <ListBase> and <List>

Problem

Our components and hooks can't leverage the offline support provided by Tanstack Query.

Solution

• Make sure our data loading hooks returns the data needed to detect those cases
• Provide components, hooks and props allowing to handle offline scenarios
• Provide default offline components in ra-ui-materialui

How To Test

• <ListBase>
• <List>
• Tests

Additional Checks

• The PR targets master for a bugfix or a documentation fix, or next for a feature
• The PR includes unit tests (if not possible, describe why)
• The PR includes one or several stories (if not possible, describe why)
• The documentation is up to date

Also, please make sure to read the contributing guidelines.

Before this change, the content was never shown when isAuthPending was true. Now, it can be. I know we did the same with ShowBase and EditBase, but I wanted to be sure that it is done on purpose: if someone provided null to hide the content while authentication is pending, it will now show the content instead of hiding it.

I actually realize I introduced the same regression in EditBase and ShowBase... PR imcoming. Regarding your comment, you're right and that's what we decided with @fzaninotto. Might be worth to discuss it again before releasing.
