[v2,00/18] devtool: ide-sdk: add support for Rust recipes

Hello, this series introduces support for Rust ide-sdk VS Code
configuration against the Yocto cross-compilation toolchain:

 - editor symbol resolution and linting
 - build task
 - deploy task
 - debugging

It introduces a cargo-example recipe following the model used for
cmake and meson.

The generated configurations can be portable to standalone SDK
installations by manually updating the paths.

C/C++ IntelliSense could provide navigation for native code compiled
by Cargo build scripts, using the recipe compiler and sysroot. This
first series defers it because no mixed-language fixture is available
to validate that workflow.

BitBake generates the Cargo configuration consumed by ide-sdk. This series
updates the parsed configuration and writes its supported TOML values
without adding a new dependency.

I reproduced the selftest coverage expected from other recipe classes,
including configuration analysis up to actual debugging symbol resolution.

I largely used AI generation to write this stack. After many iterations,
I am finally happy with the code and commit history quality of this series.
I also have a documentation commit ready for the manual if this gets
approved.

Any feedback is appreciated. Hope this will help lots of Rust developers
working with Yocto distros :).

Cheers,
Enguerrand de Ribaucourt
