[mle] define constant for "Child ID Response" timeout (#8536)

Browse Source 
This commit defines `kChildIdResponseTimeout` as a new constant
in `mle_types.hpp` which is used as maximum wait time to receive
a "Child ID Response" message from parent during attach. This
commit also removes the now unused `kMaxChildUpdateResponseTimeout`.
