This also caused un-ordered sliced prefetches to crash as they rely on Window.
Regression in e16d0c176e9b89628cdec5e58c418378c4a2436a 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.

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

LocaleMiddleware didn't handle the ValueError raised by
get_supported_language_variant() when language codes were
over 500 characters.

This is the exact same issue as refs #30408 but for creating a model with a
constraint containing % escapes instead of column addition. All of these issues
stem from a lack of SQL and parameters separation from the BaseConstraint DDL
generating methods preventing them from being mixed with other parts of the
schema alteration logic that do make use of parametrization on some backends
(e.g. Postgres, MySQL for DEFAULT).
Prior to the addition of Field.db_default and GeneratedField in 5.0
parametrization of DDL was never exercised on model creation so this is
effectively a bug with db_default as the GeneratedField case was addressed by
refs #35336.
Thanks Julien Chaumont for the report and Mariusz Felisiak for the review.

Accessing generated field values on unsaved models caused a crash when
validating CheckConstraints and UniqueConstraints with expressions.

This work improves the accessibility of the add and change pages in the
admin site by adding <details> and <summary> elements to the collapsible
fieldsets. This has the nice side effect of no longer requiring custom
JavaScript helpers to implement the fieldsets' show/hide capabilities.
Thanks to James Scholes for the accessibility advice, and to Sarah Boyce
and Tom Carrick for reviews.

FieldCacheMixin is used by related fields to track their cached values.
This work migrates get_cache_name() to be a cached property to optimize
performance by reducing unnecessary function calls when working with
related fields, given that its value remains constant.

This also introduces Expression.constraint_validation_compatible that
allows specifying that expression should be ignored during a constraint
validation.
