Benchmark activity Android

[louwers]

Add Benchmark activity for Android. I used the existing Java / Kotlin API for FPS measurement and a TextureView.

The World Tour Benchmark activity is available as a menu item in the test app.

You can add styles to developer-config.xml like so:

 <array name="benchmark_style_names">
   <item>Americana</item>
 </array>
 <array name="benchmark_style_urls">
   <item>https://zelonewolf.github.io/openstreetmap-americana/style.json</item>
</array>

The time it takes to call

maplibre-native/platform/android/MapboxGLAndroidSDK/src/main/java/org/maplibre/android/maps/renderer/MapRenderer.java

Line 135 in c8010db

private native void nativeRender();

is measured. Which is this method:

maplibre-native/platform/android/MapboxGLAndroidSDK/src/cpp/map_renderer.cpp

Line 155 in c8010db

void MapRenderer::render(JNIEnv&) {

Here is where the timing happens.

maplibre-native/platform/android/MapboxGLAndroidSDK/src/main/java/org/maplibre/android/maps/renderer/MapRenderer.java

Lines 85 to 103 in c8010db

	protected void onDrawFrame(GL10 gl) {
	long startTime = System.nanoTime();
	try {
	nativeRender();
	} catch (java.lang.Error error) {
	Logger.e(TAG, error.getMessage());
	}
	long renderTime = System.nanoTime() - startTime;
	if (renderTime < expectedRenderTime) {
	try {
	Thread.sleep((long) ((expectedRenderTime - renderTime) / 1E6));
	} catch (InterruptedException ex) {
	Logger.e(TAG, ex.getMessage());
	}
	}
	if (onFpsChangedListener != null) {
	updateFps();
	}
	}

We should go ahead and merge this as is, it's already very useful.
