chore(crashtracking): rename target triple to runtime platform (#1747)

# What does this PR do?

We send target triple as `target_triple` tag. This is fine, but runtime platform is a more appropriate name, and maintains parity with profiling: [feat(profiling): add runtime_platform tag automatically](#954)
