Small proxy class to support lvalue semantic of Str.substr. Holds

Builds and tests OK here, and passes the substr-as-lvalue tests here.
But I'd like to get some feedback from Patrick before it's applied.
I'd like to wait just a bit on this patch -- I'm not sure we need
or want the proxy class for this. It may be that it falls out naturally
somehow when we have "is rw" semantics implemented for subs.
OTOH, if it's an important feature that is being needed for
applications in Rakudo, let me know and I'll look at it closer
for immediate application.
"Objection!". Str.substr is only one method from S29 which declared "is
rw". And even after implementing S06's "is rw" methods it will still
require special proxy for Str.substr. And this patch provides excatly
this proxy.
