RFR: 8352906: stdout/err.encoding on Windows set by incorrect Win32 call

[Naoto Sato]

Those system property values on Windows were derived from Windows' `GetConsoleCP()` call, but they should have been taken from `GetConsoleOutputCP()`. Replacing the incorrect call with the correct one won't change any behavior, as both calls return the same value by default (`GetOEMCP()`). However, it is still the right thing to do.
