inform/detect which operating system a jdk comes from and stop this error

[sombriks]

whenever i open a java project in vscode in a different operating system, this appears:

those jdk exists, but in another machine, another operating system.

please make possible detect if jdks belongs to the current operating system so the message does not pops out.

Environment

• Operating System: it varies, try mac and linux
• JDK version: varies
• Visual Studio Code version: at least the 6 last releases
• Java extension version: latest one presents the issue

Steps To Reproduce

1. sync vscode account and settings across operating systems
2. configure distinct jvms on each OS

Current Result

The jvm marked as missing exists in another OS

Expected Result

my account works across distinct installations, that setting is platform-dependent, or at least should be

This is because we changed java.configuration.runtimes from machine to machine-overridable in #2001 . @jdneo does #2115 help with this at all ?
