The 'file:' store loader only understood DER natively. With all the
whatever to key decoders gone, direct support for other binary file
formats are gone, and we need to recreate them for this store loader.
With these changes, it now also understands MSBLOB and PVK files.
As a consequence, any store loader that handles some form of open file
data (such as a PEM object) can now simply pass that data back via
OSSL_FUNC_store_load()'s object callback. As long as libcrypto has
access to a decoder that can understand the data, the appropriate
OpenSSL object will be generated for it, even if the store loader sits
in a different provider than any decoder or keymgmt.
For example, an LDAP store loader, which typically finds diverse PEM
formatted blobs in the database, can simply pass those back via the
object callback, and let libcrypto do the rest of the work.

This replaces the older 'file:' loader that is now an engine.
It's still possible to use the older 'file:' loader by explicitly
using the engine, and tests will remain for it as long as ENGINEs are
still supported (even through deprecated).
To support this storemgmt implementation, a few internal OSSL_DECODER
modifications are needed:
- An internal function that implements most of
OSSL_DECODER_CTX_new_by_EVP_PKEY(), but operates on an already
existing OSSL_DECODER_CTX instead of allocating a new one.
- Allow direct creation of a OSSL_DECODER from an OSSL_ALGORITHM.
It isn't attached to any provider, and is only used internally, to
simply catch any DER encoded object to be passed back to the
object callback with no further checking. This implementation
becomes the last resort decoder, when all "normal"
decodation attempts (i.e. those that are supposed to result
in an OpenSSL object of some sort) have failed.
Because file_store_attach() uses BIO_tell(), we must also support
BIO_ctrl() as a libcrypto upcall.
