Fail to detect visual studio 2019 build tools for non-English locale

QtCreator is using vswhere to detect visual studio products, but if the OS is in non-English locale (e.g. Traditional Chinese), the detection failed with the message:

Could not parse json document from vswhere output.

It appears QtCreator is using the command:

vswhere -products * -prerelease -legacy -format json -utf8

The output is already in UTF-8, but SynchronousProcessResponse is using QTextCodec::codecForLocale() to parse the output, thus non-English locale will see the corrupted output.

It looks like you should somehow set the text codec to QTextCodec::codecForName("UTF8") before getting the stdOut() or just use allRawOutput()
