RFR: 8344275: tools/jpackage/windows/Win8301247Test.java fails on localized Windows platform

[Taizo Kurashige]

To resolve tools/jpackage/windows/Win8301247Test.java failure, I made "wmic" executed with "chcp 65001". This ensures that the encoding is UTF8 and that the English message "No Instance(s) Available." is output on localized windows platforms.

I have referred to the following for how to use chcp:
・chcp | Microsoft Learn at https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/chcp
・Code Page Identifiers - Win32 apps | Microsoft Learn at https://learn.microsoft.com/en-us/windows/win32/intl/code-page-identifiers

After fix, I ran tools/jpackage tests importing jdk.jpackage.test.Executor or jdk.jpackage.test.WindowsHelper.killAppLauncherProcess on Windows Server 2019 (Japanese and English locales). I confirmed that they pass.

Thanks
