Remove X509_to_X509_REQ.
The manual construction of the version integer is odd. The default is
already zero, and as of
https://boringssl-review.googlesource.com/c/boringssl/+/51632, we've
settled on the empty string as the ASN1_INTEGER representation of zero.
But there don't seem to be any uses of this function, so just remove it.
Update-Note: Removed seemingly unused public API.
