[NUnitLite] fix many warnings (#9959)

This project had many warnings similar to 18af3ac:

    src\Xamarin.Android.NUnitLite\Gui\Instrumentations\TestSuiteInstrumentation.cs(93,5):
    warning CA1416: This call site is reachable on all platforms. 'Bundle.PutInt(string?, int)' is only supported on: 'Android' 21.0 and later. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1416)

Basically, every call to an Android API emits this warning.

This analyzer relies on `AssemblyInfo.cs` to determine the
`$(SupportedOSPlatformVersion)` value. `$(GenerateAssemblyInfo)=false`
appears to break this analyzer!

Since `src-ThirdParty\NUnitLite\AssemblyInfo.cs` sets some of these
values, we can opt out of specifically:

    <GenerateAssemblyCompanyAttribute>false</GenerateAssemblyCompanyAttribute>
    <GenerateAssemblyConfigurationAttribute>false</GenerateAssemblyConfigurationAttribute>
    <GenerateAssemblyProductAttribute>false</GenerateAssemblyProductAttribute>
    <GenerateAssemblyTitleAttribute>false</GenerateAssemblyTitleAttribute>
    <GenerateAssemblyVersionAttribute>false</GenerateAssemblyVersionAttribute>
    <GenerateAssemblyFileVersionAttribute>false</GenerateAssemblyFileVersionAttribute>

And then the `CA1416` warnings go away.

I also fixed some trimmer warnings:

    src-ThirdParty\NUnitLite\Api\ExpectedExceptionData.cs(130,36): warning IL2070: 'this' argument does not satisfy 'DynamicallyAccessedMemberTypes.PublicMethods', 'DynamicallyAccessedMemberTypes.NonPublicMethods' in call to 'System.Type.GetMethod(String, BindingFlags, Binder, Type[], ParameterModifier[])'. The parameter 'fixtureType' of method 'NUnit.Framework.Api.ExpectedExceptionData.GetExceptionHandler(Type)' does not have matching annotations. The source value must declare at least the same requirements as those declared on the target location it is assigned to.
    src-ThirdParty\NUnitLite\Constraints\XmlSerializableConstraint.cs(56,30): warning IL2026: Using member 'System.Xml.Serialization.XmlSerializer.XmlSerializer(Type)' which has 'RequiresUnreferencedCodeAttribute' can break functionality when trimming application code. Members from serialized types may be trimmed if not referenced directly.
    src-ThirdParty\NUnitLite\Constraints\XmlSerializableConstraint.cs(56,30): warning IL3050: Using member 'System.Xml.Serialization.XmlSerializer.XmlSerializer(Type)' which has 'RequiresDynamicCodeAttribute' can break functionality when AOT compiling. XML serializer relies on dynamic code generation which is not available with Ahead of Time compilation.
    src-ThirdParty\NUnitLite\ListMapper.cs(57,29): warning IL2075: 'this' argument does not satisfy 'DynamicallyAccessedMemberTypes.PublicProperties', 'DynamicallyAccessedMemberTypes.NonPublicProperties' in call to 'System.Type.GetProperty(String, BindingFlags)'. The return value of method 'System.Object.GetType()' does not have matching annotations. The source value must declare at least the same requirements as those declared on the target location it is assigned to.

Note that I could simply remove `ListMapper.cs`, as it is not used.

I did not fix *all* of the trimmer warnings, as there are so many more.
