Per discussion with Andrew, Benoit & Egor, createPackageContext(CONTEXT_INCLUDE_CODE) from the WebApk can cause Chrome to not have its dex file optimized on O+. Since we no longer use Chrome's main dex file, just a separate dex file in the assets directory, see if we can remove the flag to CONTEXT_INCLUDE_CODE.

Of course, we only need to do this if it's sufficient to allow chrome's dex to be optimized. This is also acknowledging that for monochrome, we're not optimized anyway because of webview but this may change in future versions of android
