windows: add command line escaping wrappers around EscapeArg and CommandLineToArgv

DecomposeCommandLine makes CommandLineToArgv usable in an ordinary way.
There's actually a pure-Go version of this available as the private
os.commandLineToArgv function, which we could copy, but given this is
x/sys/windows, it seems best to stick to the actual Windows primitives
which will always remain current. Then, ComposeCommandLine is just a
simple wrapper around EscapeArg (which has no native win32 substitute).
