Temurin-build: Add x64AlpineLinux for Dragonwell 11

[joeyleeeeeee97]

We plan to add x64AlpineLinux and aarch64AlpineLinux on Dragonwell 11. (Now AdoptOpenJDK is building x64AlpineLinux hotspot in jdk16 and jdk17)

@joeyleeeeeee97 Building requires testing. Can you please open a machine request over at https://github.com/AdoptOpenJDK/openjdk-infrastructure? AFAIK we have one machine with static containers for x64. Two containers run Alpine, so they can be reused. For aarch64, nothing is available, especially with your special HW requirements.

[joeyleeeeeee97]

only x64AlpineLinux supported now.

@joeyleeeeeee97 Do you know whether the Ampere Altra has the hardware capabilities you require?

@aahlenst I can confirm that it does :-) java -version is ok on one of the Altras which I've got as part of https://github.com/AdoptOpenJDK/openjdk-infrastructure/issues/2078 :-)

The Alpine Linux team is in the process of porting Alpine to the Ampere Altra arm64 servers, targeting the 3.13 release. This is new work (as of today?). @ncopa has been leading the way there.
