clone: set submodule.recurse=true if submodule.stickyRecursiveClone enabled

Based on current experience, when running git clone --recurse-submodules, developers do not expect other commands such as pull or checkout to run recursively into active submodules. However, setting submodule.recurse=true at this step could make for a simpler workflow by eliminating the need for the --recurse-submodules option in subsequent commands. To collect more data on developers' preference in regards to making submodule.recurse=true a default config value in the future, deploy this feature under the opt in submodule.stickyRecursiveClone flag.
