[low priority] Expose functionality to enable `RUST_BACKTRACE`

[david-allison]

Should be available with

std::env::set_var("RUST_BACKTRACE", "1");

[mikehardy]

not sure this is necessary since they are standard environment variables and the Rust code shares the process (and thus the environment) with the JVM - so Kotlin code setting the env var at the Anki-Android should be sufficient

[david-allison]

Currently useless with RUST_BACKTRACE=full, and no data with RUST_BACKTRACE=1

https://github.com/ankidroid/Anki-Android/labels/Won%27t-fix Won't have the capacity to get this right, and ankidroid/Anki-Android#18512 solves this sufficiently
