Add zephyr-lang-rust as an optional module. This module brings in support for writing applications in Zephyr using the Rust programming language. At this point, the integration supports: - Building applications with Rust support. - CI testing of samples and tests from the rust module (twister functionality already present). Still to do is adding documentation to the Zephyr docs with an overview of Rust support as well as the generation of the rustdoc docs. Signed-off-by: David Brown <david.brown@linaro.org>
Although the Cmake rules for Rust leave all build files in the build directory, sometimes tools such as IDEs can leave a few files in the source tree. Ignore these to make sure they don't get committed. Signed-off-by: David Brown <david.brown@linaro.org>
Although the Cmake rules to build Rust applications keeps the target directory inside of the build directory, some IDE tools may generate a target directory while editing the code. Ignore these so they never get checked in. Signed-off-by: David Brown <david.brown@linaro.org>
Indicate that this the lang-rust module (modules/lang/rust) is maintained. Signed-off-by: David Brown <david.brown@linaro.org>
This is a little complicated. We currently just jump directly to rust's panic, so we aren't likely to actually need these unwind tables. But, they would be needed if we ever reall paniced. As of the time of this change, the tables seem to just be 24 bytes of ROM space. Signed-off-by: David Brown <david.brown@linaro.org>

I've incorporated #78901 here as it is needed to build any rust code that can possibly panic. It only affects some Cortex-M targets. |

In order to be able to ifdef based on `CONFIG_RUST`, the config must be defined in the main repo (because the rust module is optional). Add this as a placeholder. If the module is not availabe, the symbol will be present, and always disabled. The module will provide a full definition for the Kconfig. Signed-off-by: David Brown <david.brown@linaro.org>

As discussed in the 2024-09-11 TSC, this PR brings in the work on the zephyr-collab branch with that work on an external module.
With this module. The tests and samples from the rust module will be tested by CI.
