Fixed #28492 -- Defined default output_field of expressions at the class level.
...
This wasn't possible when settings were accessed during Field initialization
time as our test suite setup script was triggering imports of expressions
before settings were configured.

Refs #28492 -- Stopped accessing settings at Field.db_tablespace initialization.

Deferring accesses to settings allows database fields to be initialized before
settings are loaded.

Fixed #28543 -- Prevented ManyToManyField.value_from_object() from being lazy.
...
Previously, it was a QuerySet which could reevaluate to a new value if the
model's data changes. This is inconsistent with other Field.value_from_object()
methods.
This allows reverting the fix in the admin for refs #27998 .
