8278472: Invalid value set to CANDIDATEFORM structure

[aivanov-jdk]

According to the Windows API reference, dwStyle of CANDIDATEFORM structure should be set to CFS_CANDIDATEPOS or CFS_EXCLUDE. So, CFS_POINT is wrong here.

There are two instances in AwtComponent::SetCandidateWindow in awt_Component.cpp where the incorrect value is used.

Initially, I created this PR for jdk18. It was suggested to place this fix into the mainline, so this a continuation to jdk18/pull/54.
