[release/10.0] Fix primitive/complex collection handling on subtypes

[roji]

Fixes #37478
Simplified/targeted backport of: #37482

Description

As part of the JSON complex type work in 10.0, the navigation expansion logic for binding properties/navigations changed; unfortunately, a bug slipped in where we no longer properly take into account inheritance subtypes.

Customer impact

Queries which perform subqueries over primitive collection properties on an inheritance subtype in EF queries now fail:

var query = context.BaseTypes
    .Where(x => ((SubType)x).Ints.Any())
    .ToArray();

This isn't an uncommon scenario, and there's unfortunately no good workaround.

How found

Customer reported on EF 10.0.0.

Regression

Yes.

Testing

Test added.

Risk

Very low. The fix is very targeted and in code modified in 10.0, quirk added.

Pull request overview

This PR fixes a regression introduced in EF Core 10.0 where queries over primitive collections or complex types on inheritance subtypes fail to translate. The issue occurred when the JSON complex type work changed navigation expansion logic without properly handling inheritance scenarios.

Changes:

• Added quirk flag UseOldBehavior37478 to enable opt-out behavior for backwards compatibility
• Fixed type resolution in NavigationExpandingExpressionVisitor to check inheritance hierarchy when accessing primitive collections and complex properties on derived types
• Added comprehensive test coverage across multiple providers (base specification test, SQL Server, and Cosmos)

Customer reported regression against the latest version with targeted, quirked fix. Approved for me.
