Update vendored interface packages (#423)

* Update rclrs vendor_interfaces.py script

This updates the vendor_interfaces.py script to also vendor in the
action_msgs and unique_identifier_msgs packages. The script is modified
to always use a list of package names rather than hard-coding the
package names everywhere.

* Silence certain clippy lints on generated code

In case a user enforces clippy linting on these generated packages,
silence expected warnings. This is already the case in rclrs, but should
be applied directly to the generated packages for the sake of downstream
users.

The `clippy::derive_partial_eq_without_eq` lint was already being
disabled for the packages vendored by rclrs, but is now moved to the
rosidl_generator_rs template instead. This is necessary since we always
derive the PartialEq trait, but can't necessary derive Eq, and so don't.

The `clippy::upper_case_acronyms` is new and was added to account for
message type names being upper-case acrynyms, like
unique_identifier_msgs::msg::UUID.

* Update vendored message packages

This updates the message packages vendored under the rclrs `vendor`
module. The vendor_interfaces.py script was used for reproducibility.

The existing packages – rcl_interfaces, rosgraph_msgs, and
builtin_interfaces – are only modified in that they now use the
std::ffi::c_void naming for c_void instead of the std::os::raw::c_void
alias and disable certain clippy lints.

The action_msgs and unique_identifier_msgs packages are newly added to
enable adding action support to rclrs. action_msgs is needed for
interaction with action goal info and statuses, and has a dependency on
unique_identifier_msgs.
