Debugger: Add separator between cdb extension paths

According to
https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/
general-environment-variables
extension paths have to be separated by a semicolon.
Skipping the separator results in not being able to
debug with cdb since the debugger cannot find the
Qt Creator cdbextension in the now invalid extension path.
