RFR: 8356335: Remove linux-x86 from jib profiles

Wed May 7 07:56:53 UTC 2025

After [JEP 503](https://openjdk.org/jeps/503), we cannot build linux-x86 so it should not be included in the jib profiles. 

I also took the opportunity to remove the superfluous `--with-target-bits=64` option, clean up some `configure_args` constructs, and to reorder the profiles to group all linux profiles together.
