chore: add configure scripts and update CI

[eitsupi]

Part of #408, close #431

• Move some logics on Makevars to the configure script
• Rewrite CI workflows
• Drop R 4.1.x support (for not to use old R on Windows)

Port the configure scripts and GitHub Actions workflows from https://github.com/eitsupi/prqlr.

The release workflow seems to be building the library twice. It needs to be fixed.

Merging this PR should reduce CI execution time due to Rust caching.
I would like to do a major rewrite of the CI after this is merged.

I don't know much in bash so I can't properly review this but reducing CI time would be great. It looks like it still takes about 20min in this PR, is it because it has to rebuild everything before caching is used?

Also, I didn't understand why we bumped the required R version to 4.2. I'd rather keep it 4.1 if there are no reasons other than for CI.

I think that's why it hasn't been saved yet because the cache is only saved from the main branch.
Once this is merged and run once, the build time should be significantly faster as the binaries are cached.

To support R 4.1, the Makevars file for Windows must be split into Makevars.win and Makevars.ucrt.
Let's stop supporting R 4.1 because the cost of managing two files is high.

Also, the latest version of libR-sys no longer supports R 4.1 (extendr/libR-sys#170), so it will be necessary to end support for R 4.1 in the near future.
