Depending on the BIO used, using BIO_reset() may lead to "interesting"
results. For example, a BIO_f_buffer() on top of another BIO that
handles BIO_reset() as a BIO_seek(bio, 0), the deserialization process
may find itself with a file that's rewound more than expected.
Therefore, OSSL_DESERIALIZER_from_{bio,fp}'s behaviour is changed to
rely purely on BIO_tell() / BIO_seek(), and since BIO_s_mem() is used
internally, it's changed to handle BIO_tell() and BIO_seek() better.
This does currently mean that OSSL_DESERIALIZER can't be easily used
with streams that don't support BIO_tell() / BIO_seek().
Fixes #12541
