fix(android): saveToPhotoGallery function targeting Android 10

[garymathews]

• saveToPhotoGallery should function correctly when targeting Android 10+
• File. createTempFile causes issues on Android 10+ when attempting to create a file on external storage
• It is not necessary to immediately create a file, only the File instance is necessary, preventing a permissions error
• Utilize ContentResolver and MediaStore to access external media files

NOTES

• It was not necessary to support scoped storage access

TEST CASE

(Test the below on Android 10.0 and Android 4.4.)

const win = Ti.UI.createWindow();

function takePicture() {
    Ti.Media.showCamera( {
        success(e) {
            console.log('showCamera: success!');
            win.backgroundColor = 'orange';

            Ti.Media.saveToPhotoGallery(e.media, {
                success(e) {
                    console.log('saveToPhotoGallery: success!');
                    win.backgroundColor = 'green';
                },
                error(e) {
                    console.error(e);
                    win.backgroundColor = 'red';
                }
            });
        },
        cancel(e) {
            console.warn(e);
        },
        error(e) {
            console.error(e);
            win.backgroundColor = 'red';
        },
        saveToPhotoGallery: true,
        mediaTypes: [ Ti.Media.MEDIA_TYPE_PHOTO ]
    });
}

win.addEventListener('click', _ => {
    if (Ti.Media.hasCameraPermissions()) {
        takePicture();
        return;
    }
    Ti.Media.requestCameraPermissions(e => {
        if (!e.success) {
            console.warn('Failed to get permissions.');
            win.backgroundColor = 'red';
            return;
        }
        takePicture();
    });
});
 
win.open();

• Should not see Failed to create file: Permission denied
• Both images and videos should be present in gallery

@jquick-axway Ready for review. I also gave MediaModule.java a quick refactor, removing redundant/poor code.
