chore: regenerate cbindgen headers and Cargo.lock for libdatadog v1 FFI

Regenerate components-rs/*.h and Cargo.lock against the rebased libdatadog
submodule (v1 send FFI branch merged with libdatadog main). Picks up the
RemoteConfig DEBUG product enum, the v1 FFI comment trims, the agent_info
doc-comment tightening, and the zrip/ring lockfile additions.
