* Add trimming attributes to the Runtime XAML Loader project * Create CompilerDynamicDependenciesAttribute with all known dynamic types * Use master XamlX * Implement CompilerDynamicDependenciesGenerator to simplify CompilerDynamicDependencies attribute * Better formatting of generated code * Be safe about type converters as well * Remove unnecessary warning * Also include FindType just in caserelease/11.0.5-rc1
