RFR: 8300805: Update autoconf build-aux files with latest from 2022-09-17

[Erik Joelsson]

For a long time, we have been stuck with very old versions of the autoconf build-aux (config.guess and config.sub) files. Now we have legal approval for updating these files to versions 2022-09-17.

I have gone through all the modifications we are currently applying through the wrappers and removed those that aren't needed anymore. Most could be removed, but for some we seem to have defined our own platform standard. This means we won't be getting rid of the wrapper files anytime soon, if ever. We will likely be able to update the autoconf provided files more frequently in the future however.

I tested config.guess by putting my own `uname` shell script in the path to emulate the output for different platforms. It would still be good if people supporting the more unusual platforms could verify that they still work.
