Rely on Windows to generate CF_TEXT when active code page is UTF-8
It's possible since Windows 10 1903 to set the active code page
to UTF-8 using the manifest. In that mode, QString::toLocal8Bit
converts to UTF-8 and the legacy programs not using UTF-8 codepage
can't interpret the value.
We can detect whether the UTF-8 code page is used, and in that case
only provide data as CF_UNICODETEXT. Windows will then synthesize the
CF_TEXT format when the clipboard data is consumed, using the right code
page for the target application.
