rerun: add C++ SDK support, build librerun_c from source 

This commit adds C++ SDK support to the rerun package by:

- Building librerun_c.a library from Rust source (crates/top/rerun_c)
  instead of using prebuilt binaries
- Installing C++ headers to the dev output
- Installing CMake configuration files for integration
- Propagating arrow-cpp as a build dependency

This enables C++ developers to use Rerun without GLIBC compatibility
issues from prebuilt binaries. The library is now compiled fresh during
each build with the system's toolchain.

Package now provides:
- out: rerun CLI binary + librerun_c.a (48MB, built from source)
- dev: C++ headers + CMake config files
