Dropping an index is a schema change of its base table and
a schema drop of the index's materialized view. This combination
of schema changes used to cause issues during view building, because
when a view schema was dropped, it wasn't getting updated with the
new version of the base schema, and while the view building was
in progress, we would update the base schema for the base table
mutation reader and try generating updates with a view schema that
wasn't compatible with the base schema, failing on an `on_internal_error`.
In this patch we add a test for this scenario. We create an index,
halt its view building process using an injection, and drop it.
If no errors are thrown, the test succeeds.
The test was failing before https://github.com/scylladb/scylladb/pull/23337
and is passing afterwards.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
