feat: update build process

[matthewkeil]

Motivation
Had some issues with compilation of rust bindings for hashtree-js which is a node.js wrapper around this lib. The rust bindings did not build for Windows

Inclusions

• Fix build.rs to compile on Windows
• Update Makefile
  • Make platform selection more robust so its not necessary to pass in which CC for default situations
  • Allow for passing CC for cross-compilation situations
  • unify objarm and objx86 into OBJ_LIST dependent on platform
• Add Dockerfile for compiling and testing rust bindings on linux-arm64
• Update workflow.yaml to test for more cases of both the base lib and the rust bindings.

As a note, this step can be replaced with an action

      - name: Install
        uses: dtolnay/rust-toolchain@stable
        if: ${{ !matrix.settings.use-docker }}
        with:
          toolchain: stable
          targets: ${{ matrix.settings.target }}

I had a hard time finding a container that was easy to setup for building Windows on arm64. I suppose if someone wants in the future should be easy enough to turn on but ran out of time and just commented this case out.

I also got x86 musl building natively and with rust, but not sure if you want to include that. I had trouble with arm but also didnt try super hard because its sort of a minority architecture. Could be turned on but wasnt sure of the implications relative to the assembly in the lib. I think they are compatible and its just the build tooling and abi layout that changes. Honestly, I'm not super familiar with musl is why I removed it.

are you using the rust bindings in js?

[matthewkeil]

are you using the rust bindings in js?

Yes @arnetheduck. In ChainSafe/hashtree-js#3

Are using a submodule from the branch this PR is built from but will move to the crate once its published.

Would you mind rerunning that linux/arm64 build that was hanging as a sanity check they are all working here. I ran in my fork but would love to see the green check here too

@matthewkeil ah curious - I would have thought that the C files are both easier to use and "thinner" in terms of compiler support that's needed to get to the finish line - what motivates the use of rust in this case?

Our bindings were built with napi-rs in rust for this project, as a trial, to see how that library did from a DX perspective. Building JS binding with c++ is a bear of a job. Big picture, if we can move to rust we think it'll be better (at least we hope).

Thanks so much for this one, after offline discussions this looks good to me
