[MetalPerformanceShaders] Neural Networks Update to Xcode 11 (xamarin…
…#8844) * [MetalPerformanceShaders] Neural Networks Update to Xcode 11 This includes updates from PRs xamarin#6932, xamarin#6935 and xamarin#7461 It adds new functionality to the neural network components. This is still not the complete API for 11.3 * Update src/metalperformanceshaders.cs Co-Authored-By: Rolf Bjarne Kvinge <[email protected]> * Make changes requested by @rolfbjarne * Fix binding of default random distribution creation The parameterless function creates new default distributions and is not a property. It is a counterpart of CreateUniform. * Expose public APIs for MPSCnnConvolutionTransposeNode These APIs are public and documented at: https://developer.apple.com/documentation/metalperformanceshaders/mpscnnconvolutiontransposenode/2942641-initwithsource?language=objc I have also tested that they work. * Reintroduce compat API. * Fix acronym casing. * Fix introspection tests. * Fix xtro. * One last xtro issue. * Fix more xtro. * Another introspection fix. Co-authored-By: Frank A. Krueger <[email protected]> Co-authored-by: Rolf Bjarne Kvinge <[email protected]> * Apply suggestions from code review Co-authored-by: Rolf Bjarne Kvinge <[email protected]> * Apply feedback * Please the typo guardians Co-authored-by: Frank A.
