8348625: [21u, 17u] Revert JDK-8185862 to restore old java.awt.headless behavior on Windows

[RealCLanger]

Hi all,

This pull request contains a backport of commit e1967d51 from the openjdk/jdk21u-dev repository.
The commit being backported was authored by Christoph Langer on 31 Jan 2025 and was reviewed by Severin Gehwolf.

The patch is clean, but in 17 there is no FreeTypeScalerJNICheck.java so the bots don't recognize this.

Thanks!
