Move child resource method params next to method declarations

[pakrym-stripe]

In node, child service methods are inlined into parent service. Before this change ***Params types for child service params were generated in ChildService.ts after this change they move next to method declaration into ParentService.ts. It's not a breaking change.

Checked that all changes are equivalent by running

git diff master types/ | grep '^[-] ' | cut -c 2- | sort > /tmp/removed
git diff master types/ | grep '^[+] ' | cut -c 2- | sort > /tmp/added
diff /tmp/added /tmp/remove
