TowyTowy 2293d2f60a Fix crash when sorting by a nullable field missing on some items ...

Sorting by a field whose declared type is nullable (its null value is
`None`, e.g. `NullInteger`/`NullFloat`) raised `TypeError: '<' not
supported between instances of ...` when the field was present on some
objects but missing on others, because `FieldSort.sort` compared `None`
against real values.

Group missing values together in the sort key so they are never compared
against present ones: they are ordered first when sorting ascending and
last when descending, matching SQLite's default ordering of NULLs used by
the fast `FixedFieldSort` path.

Fixes #3461.
