RFR: 8349399: GHA: Add static-jdk build on linux-x64

[Jiangli Zhou]

Please review this change that adds a `linux-x86-static` job in GHA. The job builds the `static-jdk-image` release binary on linux-x64. Please see  https://mail.openjdk.org/pipermail/build-dev/2025-February/048830.html for some additional context.

A `debug` build job (building `static-jdk-image` fastdebug binary) is not included currently. There is a known issue that causes build failure due to resource problem, which causes the `fastdebug` build fail in github workflow. Please see more related information in https://bugs.openjdk.org/browse/JDK-8349399?focusedId=14749789&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14749789.
