Create libcrypto support for BIO_new_from_core_bio()

Previously the concept of wrapping an OSSL_CORE_BIO in a real BIO was an
internal only concept for our own providers. Since this is likely to be
generally useful, we make it a part of the public API.

Add a real type for OSSL_CORE_BIO which is distinct from and not castable to BIO

Providers (particularly the FIPS provider) needs access to BIOs from libcrypto.
Libcrypto is allowed to change the internal format of the BIO structure and it
is still expected to work with providers that were already built. This means
that the libcrypto BIO must be distinct from and not castable to the provider
side OSSL_CORE_BIO.

Unfortunately, this requirement was broken in both directions. This fixes
things by forcing the two to be different and any casts break loudly.

Add new filter BIO BIO_f_readbuffer()

This allows BIO_tell() and BIO_seek() to work for BIO's that do
not support these methods. The main use case for this is file/fd BIO's
that use stdin.

This works for stdin taken from input redirection (command < file),
and stdin via pipe (cat file | command).

Also, have it always be built, even though it's only (currently) used
on VMS. That will assure it will get the same changes as all others.
