[android] Support KEY_MAX_INPUT_SIZE configurable from the webapp

1. Add an h5vcc setting "Media.MaxInputSize" to allow the web app to explicitly set the MediaFormat.KEY_MAX_INPUT_SIZE.
2. This can also be set via MIME attribute "maxinputsize".
3. Use -1 for default value. It the setting value is smaller than default value, it will be ignored.
