Tomasz Grabiec ae8d2a550d db: schema_tables: Make table creation shadow earlier concurrent changes
Issuing two CREATE TABLE statements with a different name for one of
the partition key columns leads to the following assertion failure on
all replicas:

scylla: schema.cc:363: schema::schema(const schema::raw_schema&, std::optional<raw_view_info>): Assertion `!def.id || def.id == id - column_offset(def.kind)' failed.

The reason is that once the create table mutations are merged, the
columns table contains two entries for the same position in the
partition key tuple.

If the schemas were the same, or not conflicting in a way which leads
to abort, the current behavior would be to drop the older table as if
the last CREATE TABLE was preceded by a DROP TABLE.

The proposed fix is to make CREATE TABLE mutation include a tombstone
for all older schema changes of this table, effectively overriding
them. The behavior will be the same as if the schemas were not
different, older table will be dropped.

Fixes #11396
