  * dotnet/java-interop@bbaeda6f: [Java.Interop] Support Desugar + interface static methods (dotnet/java-interop#1077)

Context: dotnet/java-interop@bbaeda6
Context: dotnet/java-interop@1f27ab5
Context: f6f11a5

[Desugaring][0] is the process of rewriting Java bytecode so that
Java 8+ constructs can be used on Android pre-7.0 (API-24), as
API-24 is the Android version which added native support for Java 8
features such as [interface default methods][1].

One of the implications of desugaring is that methods can "move";
consider this Java interface:

	package example;
	public interface StaticMethodsInterface {
	    static int getValue() { return 3; }
	}

Java.Interop bindings will attempt to invoke the `getValue().I`
method on the type `example/StaticMethodsInterface`:

	public partial interface IStaticMethodsInterface : IJavaObject, IJavaPeerable {
	    private static readonly JniPeerMembers _members = new XAPeerMembers ("example/StaticMethodsInterface", typeof (IStaticMethodsInterface), isInterface: true);
	    static unsafe int Value {
	        get {
	            const string __id = "getValue.()I";
	            var __rm = _members.StaticMethods.InvokeInt32Method (__id, null);
	            return __rm;
	        }
	    }
	}

The problem is that, after Desugaring, the Java side *actually* looks
like this:

	package example;
	public interface StaticMethodsInterface {
	}
	public class StaticMethodsInterface$-CC {
	    public static int getValue() {return 3;}
	}

Commits dotnet/java-interop@1f27ab55 and f6f11a5 added partial
runtime support for this scenario via
`AndroidTypeManager.GetStaticMethodFallbackTypesCore()`, which would
attempt to lookup types with a `$-CC` suffix.

While this was a good start, it wasn't ever actually *tested*
end-to-end.  Consequently, instead of *working*, this would instead
cause the process to *abort*:

	JNI DETECTED ERROR IN APPLICATION: can't call static int example.StaticMethodsInterface$-CC.getValue() with class java.lang.Class<example.StaticMethodsInterface>
	    in call to CallStaticIntMethodA
	    from void crc….MainActivity.n_onCreate(android.os.Bundle)

Oops.

dotnet/java-interop@bbaeda6f improves our runtime support for
invoking *`static`* methods on interfaces.

Add a new `XASdkDeployTests.SupportDesugaringStaticInterfaceMethods()`
test which performs an on-device, end-to-end invocation of a static
method on a Java interface, to ensure that things *actually* work.

*Note*: if `$(SupportedOSPlatformVersion)` is 24 or higher, this test
will work even without dotnet/java-interop#1077, as Desugaring is
*disabled* in that case.

The test `JniPeerMembersTests.DesugarInterfaceStaticMethod()` added
in dotnet/java-interop@bbaeda6f attempts to "fake" a Desugar
environment for testing on Desktop Java, and this "fakery" doesn't
work in the Android environment.  Fix execution on Android by updating
`AndroidRuntime.GetStaticMethodFallbackTypesCore()` to support type
remapping (f6f11a5) -- which was overlooked/not considered --
such that the types returned are *after* calling
`AndroidRuntime.GetReplacementTypeCore()`, which looks up
`<replace-type/>` values.  This allows us to remap
`AndroidInterface` to `DesugarAndroidInterface$_CC`, allowing the
`DesugarInterfaceStaticMethod()` test to pass.

Update the `BuildTestJarFile` target so that it properly builds files
that contain `$` on Unixy platforms.
