rust: adapt `alloc` crate to the kernel This customizes the subset of the Rust standard library `alloc` that was just imported as-is, mainly by: - Adding SPDX license identifiers. - Skipping modules (e.g. `rc` and `sync`) via new `cfg`s. - Adding fallible (`try_*`) versions of existing infallible methods (i.e. returning a `Result` instead of panicking). Since the standard library requires stable/unstable attributes, these additions are annotated with: #[stable(feature = "kernel", since = "1.0.0")] Using "kernel" as the feature allows to have the additions clearly marked. The "1.0.0" version is just a placeholder. (At the moment, only one is needed, but in the future more fallible methods will be added).

rust: alloc: clarify what is the upstream version It may be unclear for readers which upstream Rust version these files are based on. They may be unaware that they are intended to match the minimum (and only, so far) supported version of Rust in the kernel. Thus clarify it.
