Update cppbuild to ensure container has cmake and rapidjson dependencies

Since this modifies the system, please add that to the workflow instead

@saudet This is only for when people want to use javacpp directly within the Triton container. Currently they need to apt get gpg wget rapidjson-dev cmake before they do:

git clone https://github.com/bytedeco/javacpp-presets.git
cd javacpp-presets
mvn clean install --projects .,tritonserver
mvn clean install -f platform --projects ../tritonserver/platform -Djavacpp.platform.host

With the current changes the system installations are done with cppbuild.sh.

If you feel strongly against this change, we can add additional install instructions for TritonCPP + Javacpp on the README on the Triton side.

Then that's problem with the Docker image of Triton. That should probably be added to this file maybe?

The developer_tools related bindings are not installed in the Triton container or the Triton SDK container by choice. I don't think it makes sense to install more dependencies in anticipation the the user will use CAPI bindings or Java CAPI bindings

[saudet]

I suppose, but you could offer other container images that do have the required build dependencies. Anyway, most Java developers don't build from source, so this isn't something we need. Just offer prebuilt binaries and they will use those.

Yep we provide the jars anyway and they can use the bytedeco pre-built binaries. Just wanted a complete set of build instructions so closing this PR and instead submitting #1413 for review 🙏
