chore: avoid repackaging of google elemental dep and use it directly (#12459)

(#12416)

The google elemental dependency is not OSGi compatible so it's
repackaged into shared module to use it directly from there. But there
is a custom Vaadin version of google elemental dep and it's OSGi
compatible. Flow uses this version and to be able to use FW in MPR the
versions should match. So the Vaadin google elemental dep is added
instead of repackaging.
