vendor: go get github.com/zclconf/go-cty@master 

This fixes some consistency problems with how number strings were parsed
in the msgpack decoder vs other situations.

This commit also includes an upgrade of HCL2 to use this new cty function,
though there's no change in behavior here since the new function is
functionally equivalent to what it replaced.
