df236b0bcb [5.1.x] Fixed #35665 -- Fixed a crash when passing an empty order_by to Window. 
This also caused un-ordered sliced prefetches to crash as they rely on Window.

Regression in e16d0c176e that made OrderByList
piggy-back ExpressionList without porting the empty handling that the latter
provided.

Supporting explicit empty ordering on Window functions and slicing is arguably
a foot-gun design due to how backends will return undeterministic results but
this is a problem that requires a larger discussion.

Refs #35064.

Thanks Andrew Backer for the report and Mariusz for the review.

f030236a86 Fixed #35275 -- Fixed Meta.constraints validation crash on UniqueConstraint with OpClass(). 
This also introduces Expression.constraint_validation_compatible that
allows specifying that expression should be ignored during a constraint
validation.

Also removed tests that ensured that adapt_(date)timefield backend
operations where able to deal with expressions when it's not the case
for any other adapt methods.

40b8a6174f Fixed #33397 -- Corrected resolving output_field for DateField/DateTimeField/TimeField/DurationFields. 
This includes refactoring of CombinedExpression._resolve_output_field()
so it no longer uses the behavior inherited from Expression of guessing
same output type if argument types match, and instead we explicitly
define the output type of all supported operations.

This also makes nonsensical operations involving dates
(e.g. date + date) raise a FieldError, and adds support for
automatically inferring output_field for cases such as:
* date - date
* date + duration
* date - duration
* time + duration
* time - time

0ed2919814 Fixed #33406 -- Avoided creation of MaxLengthValidator(None) when resolving Value.output_field for strings. 
This brings the behaviour in line with Field subclasses which append to
the validators within __init__(), like BinaryField, and prevents the
creation of a validator which incorrectly throws a TypeError, if it
were used.
