Android: Make is possible to change setAllowFileAccess()
Before API level 30 the WebView on Android allowed file access, but that
has since been turned off by default. As a bare minimum we can allow
the user that has been depending on local file access to revert that
by setting an environment variable.
Fixes: QTBUG-97487
