Calling Expression.Lambda without a delegate type isn't AOT compatible. Fix this by passing the delegate type.

Customer Impact
When customers use the native AOT Roslyn Analyzer to find AOT incompatible code, they are not getting the warnings correctly for System.Linq.Expressions. This degrades the value of the Roslyn Analyzer.
By adding these attributes to the
refassemblies, this allows the Roslyn Analyzers to work correctly and raise warnings where customer code is calling AOT-incompatible APIs.Regression
[If yes, specify when the regression was introduced. Provide the PR or commit if known.]
Testing
The change to Microsoft.Extensions.DependencyInjection in our repo was because the Roslyn Analyzer found a place where we were calling an incompatible API. This verifies that the ref assembly is correctly attributed.
All existing automated tests pass.
Risk
Low. The change to Linq.Expressions is only to put the matching attributes in the ref assembly from the implementation assembly. This only affects compilation and won't affect runtime behavior. The change to Microsoft.Extensions.DependencyInjection was verified by existing tests and is in code that is only used in
netstandard2.0builds, not in .NET Framework or .NET Core builds.
