Regression in 8b93b31487d6d3b0fcbbd0498991ea0db9088054.

Used migration framework in GIS test tearDown
Added Spatialite support to the new migration framework

Refs #22451.
Fixed #22495 -- Locmem cache.add() failed with infinite timeouts

cache.add() incorrectly succeeded when there was an existing key
with an infinite (None) timeout.
Set compile messages options as class variable

Refs #18714. Same logic as options for makemessages commands.
Wrapped migrations in a transaction only on DBs with transactional DDL.
Used the same instance of atomic for entry and exit.

Since all state is maintained on the connection at this time and none in
the atomic, it doesn't matter, but it could introduce some subtle bugs
if the implementation changed in the future.
Fixed #21157 -- Fixed problems with ResolverMatch

- Fixed bug in get_callable() that caused resolve() to put a string
  in ResolverMatch.func.
- Made ResolverMatch.url_name match the actual url name (or None).
- Updated tests that used the string value in ResolverMatch.func, and
  added regression tests for this bug.
- Corrected test urls whose dummy view paths caused failures (behavior
  that was previously masked by this bug).
