[Xamarin.Android.Build.Tasks] Remove MAM targets from CoreResolve (#7868)

Context: f6f11a5

We're working with the InTune team to make use of our member remapping
support (f6f11a5), and they hit a bit of a snag:

> I'm having some issues integrating it into the Xamarin build.
> We need our process to run after `_CompileJava` so we can analyze
> the inheritance of the app's classes. Now, we also need our process
> to run before `_CollectAndroidRemapMembers` so that the XML
> generated in that process can be consumed properly. Unfortunately,
> this generates a circular dependency:
>
>     error MSB4006: There is a circular dependency in the target dependency graph
>       involving target "_CollectAndroidRemapMembers".
>       Since "_ResolveLibraryProjectImports" has "DependsOn" dependence on
>       "_CollectAndroidRemapMembers", the circular is
>       "_CollectAndroidRemapMembers<-_ResolveLibraryProjectImports<-_ExtractLibraryProjectImports<-_GetLibraryImports<-_CompileJava<-…<-_CollectAndroidRemapMembers".

Commit f6f11a5 updated `$(CoreResolveReferencesDependsOn)` to add
the `_ConvertAndroidMamMappingFileToXml` and `_CollectAndroidRemapMembers`
targets, but @jonpryor does not remember *why* these targets needed
to be added to `$(CoreResolveReferencesDependsOn)` in the first place.

Update `$(CoreResolveReferencesDependsOn)` to remove the
`_ConvertAndroidMamMappingFileToXml` and `_CollectAndroidRemapMembers`
targets, and move those targets to the new
`$(_GenerateAndroidRemapNativeCodeDependsOn)` MSBuild property, which
is the `DependsOnTargets` list for the target
`_GenerateAndroidRemapNativeCode`.  This delays execution of the
`_ConvertAndroidMamMappingFileToXml` and `_CollectAndroidRemapMembers`
targets as late as possible, which should resolve the circular deps.
