[TIMOB-27695] Android: Heavy image processing methods do not trigger GC

const win = Ti.UI.createWindow({ backgroundColor: 'gray' });
const img = Ti.UI.createImageView();

win.addEventListener('open', async () => {

    // Obtain large image blob. (8205px, 11750px)
    let blob = await getImage('https://tinyurl.com/rxob7ju');

    // Keep re-sizing the image down by 10%
    for (let i = 0; i < 10; i++) {

        // De-reference original blob so it can be freed.
        blob = blob.imageAsResized(blob.width / 1.1, blob.height / 1.1);

        // Idle for 100ms, allowing V8 GC to collect.
        // QE: Should not need to do this to display image.
        // await new Promise(resolve => setTimeout(resolve, 100));
    }

    // Display re-sized image.
    img.image = blob;
});

win.add(img);
win.open();

function getImage(url) {
    return new Promise((resolve, reject) => {
       const client = Ti.Network.createHTTPClient({
            onload(e) {
                resolve(e.source.responseData);
            },
            onerror: reject,
            timeout : 10000
        });
        client.open('GET', url);
        client.send();
