Configuration: produce include/openssl/configuration.h when configuring

Configuration: produce include/openssl/configuration.h when configuring

The goal is to avoid having too much of the OpenSSL source rebuilt
because include/openssl/configuration.h, or even because it was a
Makefile target that was called upon (some make implementations
consider the use of a target as an update of that target, even if it
wasn't really updated).

To resolve this, we move the production of include/openssl/configuration.h
to configdata.pm, and only update it if there were any actual changes.

Fixes #16377
