* [tests] Minor refactor to get better Xcode version parsing.
* Rename Configuration.XcodeVersion to XcodeVersionString.
* Add Configuration.XcodeVersion a parsed Version instane of XcodeString.
* [tests] Ignore all 'MT0099: Not linking with WatchKit because Xcode 11 beta 1' warnings in tests.
* [tests] Adjust min OS version tests for Xcode 11b1.
* [tests] Adjust tests for changes in 'nm' output.
* [tests] Adjust tests for name changes in Clang.
* [tests] Adjust tests for changes in ld warning format.
* [msbuild] 'metal' and 'metallib' aren't in PATH anymore, so use xcrun to execute them.
* [msbuild] Fix DevicePlatformBinDir for the Metal and MetalLib targets on iOS.
Also set the SDKROOT variable, otherwise metal and metallib don't work
properly, and revert the previous attempt at a fix (use xcrun).
* [tests] Simplify version parsing code to not version parse anymore.
* [tests] Add FIXME for once Apple fixes the WatchKit disappearance.
* [msbuild] Pack all iOS MSBuild Task assemblies into a single assembly
* Fixed the build
* Renamed ProcessArgumentBuilder to CommandLineArgumentBuilder
This is needed to prevent symbol conflicts with Xamarin.MacDev's
ProcessArgumentBuilder (which is functionally different from
Xamarin.MacDev.Tasks.Core's class of the same name).
* Fixed ILRepack logic for filtering dll's to repack
* Fixed building of Xamarin.iOS.Tasks.Tests now that X.iOS.Tasks.dll contains all symbols
* Updated Makefile now that only 1 iOS Task assembly needs to be distributed
* ILRepack Xamarin.Mac.Tasks as well
* Fixed up *.targets to specify The One Assembly To Rule Them All
* [xharness] Build MSBuild tests with MSBuild.
* Touch the ilrepack stamp file *after* invoking ILRepack, not before.
* Same for Xamarin.Mac.Tasks
