8369032: Add test to ensure serialized ICC_Profile stores only necessary optional data

[mrserb]

Hi all,

This pull request contains a backport of commit ed153ee2 from the openjdk/jdk repository.

The backport is mostly clean: I have to update the test to use explicit types in SerializedFormSize instead of var.

The commit being backported was authored by Sergey Bylokhov on 21 Oct 2025 and was reviewed by Harshitha Onkar.
