[mini-1235]

In Nav2, we are building BT.CPP from source temporarily, however, we are failing to build now:

I believe this is because tinyxml2_vendor is deprecated and removed on rolling, so I am removing this in rolling.

It looks like the issue is also due to rolling moved to Ubuntu Resolute, this causes issue when running rosdep on Noble. But I still think this PR is useful, since tinyxml2_vendor is expected to be removed in the future (if I remember correctly, around the Lyrical release)

CMake Deprecation Warning at /opt/ros/rolling/share/tinyxml2_vendor/cmake/tinyxml2_vendorConfig.cmake:34 (message):
  Package 'tinyxml2_vendor' is deprecated (This package will be removed in
  ROS 2 Lyrical Luth.  Instead, use

        distributed package which provides same functionality.)
