iox-#2011 Silence some warnings when building with GCC 13.

[clalancette]

GCC 13 (which is in Ubuntu 24.04) introduced a number of false positive warnings when using -Warray-bounds and -Wstring-op; see:

• https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114758
• https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111118
• https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110807
• https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110498

In my testing, these only show up when building with optimizations, i.e. CMAKE_BUILD_TYPE=RelWithDebInfo.

This commit silences those warnings across the two functions that cause the problem, and make the build completely clean.

Notes for Reviewer

This should fix the yellow builds in e.g. https://ci.ros2.org/view/packaging/job/packaging_linux/3451/ Note that this targets the release_2.0 branch, since that is what ROS 2 is currently using. If you'd like me to target another branch and then backport, I'm happy to do that instead.
