Subject: [PATCH 1/2] workflow: Create basic build of rust samples

Build the rust code samples to make sure that Rust support is working on
all supported targets.  This adds toolchain support and rust target
support for the supported Cortex-M, and RISC-V targets.

The workflow runs on every pull request and on every push.

Subject: [PATCH 2/2] workflow: Only run once on PR or merge to main

Restrict when the workflow is run so that it will either run when pushed
to main, or when a pull request to main, and not for arbitrary other
branches.
