[ignition-msgs1, ignition-transport4] Add new ports 🤖

[traversaro]

Write new ports using the ignition-modularscript port added in #7781 .
The ports are for the ignition-msgs ( https://ignitionrobotics.org/libs/msgs ) and ignition-transport ( https://ignitionrobotics.org/libs/transport ) libraries for robotics applications.

Related issue: #8014 .

The failures on triplets x64-uwp, arm64-windows, arm-uwp are expected, as ignition-msgs1 requires some modifications to support cross compilation, and instead of working directly on a patch I opened an issue upstream to make sure that the modification will be eventually merged upstream (see https://bitbucket.org/ignitionrobotics/ign-msgs/issues/34/add-support-for-cross-compilation).

Instead, the failure in x64-linux is quite strange, and can be investigated further, as there are some strange linking failures w.r.t. to protobuf.

[traversaro]

The x64-linux failure is apparently due to the fact that the linking order depends when linking static libraries using ld, and the order used in the build system of ignition-msgs for linking protobuf libraries was wrong, see the PR at https://bitbucket.org/ignitionrobotics/ign-msgs/pull-requests/151/fix-linking-order-of-protocol-buffers/diff for more details.

[traversaro]

In the latest commit the failure in x64-linux have been solved, and the only failures are the expected one on cross-compilation targets.

[traversaro]

There is another Linux failure because the logic to find UUID in ignition-transport4 requires pkg-config to be installed, and pkg-config is not installed in the test machines.

Fix for uuid problem described in #8044 (comment) added in the latest version of the PR.

Robot emoji added to the title (see #7781 (comment)), I think the PR is now ready for review.
