feature(views-with-tablets): enable testing materialized views with t…

…ablets

Materialized views are currently not allowed in tablet keyspaces, due to some
pending issues. However, they can be enabled using the "views-with-tablets" experimental feature.

While improving views with tablets, we should make sure that the existing tests keep passing,
so we should run materialized view (and index) tests with tablets using the experimental feature.

The feature doesn't affect tests ran on vnodes. For tablets, the tests would fail without the feature
due to unsupported configuration.

Considering that, we should enable the feature by default for all tests (with a special consideration
to upgrade tests).

The change includes:
* modifying the default experimental_features in defaults/test_default.yaml
* updating upgrade tests - for upgrades, the first version with this experimental feature will
be 2025.1, so the upgrade tests are updated to remove this feature from the defaults and to set
it when upgrading to 2025.1 or higher. When testing upgrades to future versions, we'll need to
keep the experimental_feature also for base version, with an exception for sequential upgrades,
(currently we only have 2021.1->2022.1->2023.1 test in test_custom_profile_sequential_rolling_upgrade)
where the base version of the sequence might not have this experimental feature, so we'll need
to adjust it accordingly.
