Remove //components/resources dep from //weblayer:weblayer_lib

//components/resources is a group target that both generates the headers
via grit and also generates the pakfile. The only reason that this direct
dependency would be needed from the weblayer_lib target was if the files in
weblayer_lib were including the grit-generated headers from
//components/resources (making sure that the necessary resources are
packaged in a given app is not the responsibility of weblayer_lib).
However, they're not.

Note however that //weblayer:weblayer_lib already has indirect
dependencies on //components/resources (e.g., via
//components/security_interstitials/content:security_interstitials_page),
so this change impacts only logical clarity.
