Replace `is_uses_lib` property with `provides_uses_lib`.

The previous property was boolean-valued and provided only the
information whether the library should be treated as <uses-library>
by Soong. The new property is an optional string, which is the name of
the <uses-library>. The name can be different from the module name, as
in the case of "qcrilhook" module which provides <uses-library>
"com.qualcomm.qcrilhook".
