Migrate view-query permission to SQL-based system, refs #2510

This change integrates canned queries with Datasette's new SQL-based
permissions system by making the following changes:

1. **Default canned_queries plugin hook**: Added a new hookimpl in
   default_permissions.py that returns canned queries from datasette
   configuration. This extracts config-reading logic into a plugin hook,
   allowing QueryResource to discover all queries.

2. **Async resources_sql()**: Converted Resource.resources_sql() from a
   synchronous class method returning a string to an async method that
   receives the datasette instance. This allows QueryResource to call
   plugin hooks and query the database.

3. **QueryResource implementation**: Implemented QueryResource.resources_sql()
   to gather all canned queries by:
   - Querying catalog_databases for all databases
   - Calling canned_queries hooks for each database with actor=None
   - Building a UNION ALL SQL query of all (database, query_name) pairs
   - Properly escaping single quotes in resource names

4. **Simplified get_canned_queries()**: Removed config-reading logic since
   it's now handled by the default plugin hook.

5. **Added view-query to default allow**: Added "view-query" to the
   default_allow_actions set so canned queries are accessible by default.

6. **Removed xfail markers**: Removed test xfail markers from:
   - tests/test_canned_queries.py (entire module)
   - tests/test_html.py (2 tests)
   - tests/test_permissions.py (1 test)
   - tests/test_plugins.py (1 test)

All canned query tests now pass with the new permission system.
