Refactor the provider side DER constants and writers

This splits up all the providers/common/der/*.c.in so the generated
portion is on its own and all related DER writing routines are in
their own files.  This also ensures that the DIGEST consstants aren't
reproduced in several files (resulting in symbol clashes).

Finally, the production of OID macros is moved to the generated header
files, allowing other similar macros, or DER constant arrays, to be
built on top of them.
