In Linux, `free_memory` refers MemFree (equivalent with older `available_memory`), and `available_memory` refers MemAvailable. In other platforms, `free_memory` proxies `available_memory`. And also `CompileBroker` uses `free_memory` rather than `available_memory`. Some GHA checks were failed, but I think they are not caused by this change.

@jerboaa @dholmes-ora I added comment for `available_memory` and `free_memory`. Is it enough? https://github.com/openjdk/jdk/pull/13398/commits/6aba3440131936a82daccdb65e7b241c022a21c7
