* For Xamarin.Mac, this means using the _ComputeBundleResourceOutputPaths and
_CopyResourcesToBundle targets from Xamarin.iOS instead of the
_CopyContentToBundle target (which is now unused and thus removed).
* Adapt the Xamarin.iOS logic (now shared) to handle the fact that the
resources shouldn't always go into the root appbundle directory (since they
go into Contents/Resources/ for macOS apps), by using the
'_AppResourcesPath' variable to specify just this.
Once upon a time the Xamarin.iOS logic was identical to the Xamarin.Mac logic,
but then we implemented support for asset packs
(a98693f07e)
and the code diverged. This means that unifying the logic again is a step
towards making asset packs work for Xamarin.Mac apps.
* [msbuild] Share the MSBuild logic for CollectBundleResources and a few related properties.
* [msbuild] Fix/unify more resource collection code.
* Remove the _CollectBundleResources target for Xamarin.iOS binding projects,
we now have a single one for all project types.
* Add an IsBindingProject property to distinguish binding projects from other
projects.
* Use the IsBindingProject to only depend on the other _Compile<ResourceType>
targets when we're not building a binding project (which seems to be the
reason why the _CollectBundleResources target was duplicated between normal
projects and binding projects for both Xamarin.iOS and Xamarin.Mac: the
binding project version didn't have any dependencies).
* [msbuild] Share the DeviceSpecificIntermediateOutputPath property.
We don't technically need this value for Xamarin.Mac, but many of the targets
that can be shared need to use this for Xamarin.iOS, so set this value for
Xamarin.Mac as well. It will always be the default IntermediateOutputPath for
Xamarin.Mac, while for Xamarin.iOS it might be changed in
_ComputeTargetArchitectures.
* [msbuild] Remove usage in Xamarin.Mac of a variable that was always empty in the past.
* [msbuild] Unify MtouchDebug and MmpDebug into _Debug.
* [msbuild] Use _BundlerDebug instead of _Debug.
_Debug is too generic, and more likely to clash with someone else.
* [msbuild] Unify MtouchArch and XamMacArch into TargetArchitectures.
* [msbuild] Use $(ComputedPlatform) instead of $(_Platform).
They're identical, and this avoids using $(_Platform) before it's defined.
