Tomasz Grabiec 4a83b4eef3 Merge 'topology_coordinator: abort view building a bit later in case of tablet migration' from Piotr Dulikowski
In multi DC setup, tablet load balancer might generate multiple migrations of the same tablet_id but only one is actually commited to the `system.tablets` table.

This PR moved abortion of view building tasks from the same start of the migration (`<no tablet transition> -> allow_write_both_read_old`) to the next step (`allow_write_both_read_old -> write_both_read_old`). This way, we'll abort only tasks for which the tablet migration was actually started.

The PR also includes a reproducer test.

Fixes scylladb/scylladb#25912

View building coordinator hasn't been released yet, so no backport is needed.

Closes scylladb/scylladb#26144
