Add AndroidManifest.xml intent-filters for bundled exchanges file

We are implementing "Navigation to Bundled Exchanges".
Design doc:

To open the Bundled Exchanges files on Android from other applications, we need
to add intent-filters in AndroidManifest.xml.

The first intent-filter is for the applications which can't detect the
"application/webbundle" mime type. (eg: Open .wbn file from "Internal Storage"
in Files app.) We use pathPattern to capture the ".wbn" file extension. But due
to the strange behavior of intent filter's pathPattern [1], we need to have
multiple patters to load the .wbn files under folders which name contains ".".

The second intent-filter is for the applications which can detect the
"application/webbundle" mime type. (eg: Download the Bundled Exchanges file with
"content-type: application/webbundle" header, and open the file from "Download"
category in Files app.)

We don't have plan to ship this feature in Beta and Stable yet.
So this CL uses "{% if channel in ['dev', 'canary', 'default'] %}" not to change
the AndroidManifest.xml for Beta and Stable.
