Rework how our providers are built

We put almost everything in these internal static libraries:

libcommon               Block building code that can be used by all
                        our implementations, legacy and non-legacy
                        alike.
libimplementations      All non-legacy algorithm implementations and
                        only them.  All the code that ends up here is
                        agnostic to the definitions of FIPS_MODE.
liblegacy               All legacy implementations.

libnonfips              Support code for the algorithm implementations.
                        Built with FIPS_MODE undefined.  Any code that
                        checks that FIPS_MODE isn't defined must end
                        up in this library.
libfips                 Support code for the algorithm implementations.
                        Built with FIPS_MODE defined.  Any code that
                        checks that FIPS_MODE is defined must end up
                        in this library.

The FIPS provider module is built from providers/fips/*.c and linked
with libimplementations, libcommon and libfips.

The Legacy provider module is built from providers/legacy/*.c and
linked with liblegacy, libcommon and libcrypto.
If module building is disabled, the object files from liblegacy and
libcommon are added to libcrypto and the Legacy provider becomes a
built-in provider.

The Default provider module is built-in, so it ends up being linked
with libimplementations, libcommon and libnonfips.  For libcrypto in
form of static library, the object files from those other libraries
are simply being added to libcrypto.
