Fix gcc and adoptopenjdk_install roles for riscv64

[sxa]

Fixes https://github.com/adoptium/infrastructure/issues/3634 and also adjusts the adoptopenjdk_install role to install JDK17 and 21 from the normal processes now that those levels are GA on riscv64

FYI @luhenry since you added most of the adoptopenjdk_install workarounds in the past but they shouldn't be required now :-)

You can also clean up some of https://github.com/sxa/infrastructure/blob/riscv64_fixes/ansible/playbooks/AdoptOpenJDK_Unix_Playbook/roles/Common/vars/Ubuntu.yml#L104

I would like to consider upgrading to Ubuntu 22.04 for the base image as well. AFAIK we have no downstream jobs which rely on glibc versions older 2.35.

Good shout - I've removed openjdk-17-jdk in this PR now too with the latest commit.
