[jdk11u-dev] RFR: 8292717: Clean up checking of testing requirements in configure

[Goetz Lindenmaier]

I backport this because then 8314495 can be backported clean. Also brings 11 closer to 17.

configure.ac::
I had to resolve two chunks. In one, I needed to omit the coding for JMH which is not
supported by 11.

jdk-options.m4, toolchanin.m4
Deleted function has different body, deleted by hand.

lib-tests.m4: Copyright.

The original change moves and renames three
functions to lib-tests.m4. It does not change
the implementation of these.
So I modified the added code in lib-tests.m4
to have the unchanged function bodies that
were deleted in the other files.
