fix: make color-backtrace optional for release

[hardfist]

Summary

since we use abort panic=abort in release and it will not generate meaningful backtrace, so color-backtrace seems meanless and can be removed for release profile to reduce binary size.
we can also enable panic = unwind for dev profile to help debugging panic problem in development environment
