[2.0.x] Fixed #29182 -- Fixed schema table alteration on SQLite 3.26+.

SQLite 3.26 repoints foreign key constraints on table renames even when
foreign_keys pragma is off which breaks every operation that requires
a table rebuild to simulate unsupported ALTER TABLE statements.

The newly introduced legacy_alter_table pragma disables this behavior
and restores the previous schema editor assumptions.

Thanks Florian Apolloner, Christoph Trassl, Chris Lamb for the report and
troubleshooting assistance.

Backport of c8ffdbe514b55ff5c9a2b8cb8bbdf2d3978c188f from master.
