Add LICENSE/NOTICE files to be included in jars

We currently include the root LICENSE and NOTICE file in each of the
jars that we create and distribute. However, those files define the
license of all the source code in the repository, and is not specific to
each submodule the jar represents. Furthermore, the license references
files that don't actually exist in a compiled jar. We really need a
unique LICENSE and NOTICE for each submodule we distribute to include in
each jar.

This adds those unique LICENSE and NOTICE files to submodules that we
distribute. Aside from daffodil-lib, each of these submodule includes
only Daffodil code, and so no additional licensing information is needed
aside from the standard Apache v2 license and Daffodil notice. The
LICENSE for daffodil-lib has additional information for the few things
that are included in that jar (Scala library code, XSD schema, and
passera).

Also fix "the these" typo in subcomponents blurb in license.
