[rust] Capture Rust backtrace in case of error (displayed at DEBUG le…

…vel) (#12852)

* [rust] Use anyhow crate to display backtrace in case of error

* [rust] Include --backtrace argument to enable backtrace capture

* [rust] Use --backtrace argument in test

* [rust] Enable using RUST_BACKTRACE to capture backtrace as well

* [rust] Remove --backtrace (display backtrace when error is available at DEBUG level)

* [rust] Include debug info in release artifact and enable backtrace by default

* Revert "[rust] Include debug info in release artifact and enable backtrace by default"

This reverts commit aa57f2a.

* [rust] Remove backtrace for warning message

* [rust] Remove --backtrace from test

* [rust] Fix problems after rebasing

* [rust] Update bazel lock file

* [rust] Remove old download browser function in edge module
