Subject: [PATCH 0/4] rust: alloc: vec: Add some missing fallible try_*
 methods

Hi everyone!

This short series is part of the set of dependencies for the drm/asahi
Apple M1/M2 GPU driver.

This series imports part of a commit from Miguel in
rust-for-linux/linux, which adds missing fallible
mutation/allocation methods to `Vec`. These are generally useful to make
standard features available to the kernel environment, which does not
have infallible allocation.

The additions in turn depend on importing two submodules from the Rust
stdlib, which I have attributed using the same commit message template
used for the original import of this part of the codebase. These
versions come from Rust 1.66, but also build on Rust 1.62 (the current
version upstream). I added the SPDX identifiers in a separate commit to
clearly separate the original code from subsequent changes.
