  Changed paths:
    M Configure
    M configdata.pm.in

  Log Message:
  -----------
  Configuration: only produce a new configdata.pm if it has changed contents

The goal is to avoid having too much of the OpenSSL source rebuilt
because configdata.pm got a new time stamp.  The conditions for
updating configdata.pm are now:

1.  its time stamp is older than Configure's, or...
2.  its contents has changed.

Fixes #16377

  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

  Building: For the FIPS module checksum, keep track of configuration,h

The FIPS module checksum needs to know that configuration.h is
generated from configuration.h.in, so that information is conserved.
To make this possible, it's now possible to have attributes with the
GENERATE keyword, and the attribute "skip" is added to make a keyword
a no-op, which makes it informative only.
