Improved Wasmer C API release artifacts

[syrusakbary]

Description

This PR updates the artifacts generated for Wasmer C API, in a way that is much more consumable, including a quick README and License.

So, after running make capi && make build-capi We will have a wasmer-c-api.tar.gz file with the following structure

/
  lib/
    libwasmer.a
    libwasmer.so
  include/
    wasmer.h
    wasmer.hh
  README.md
  LICENSE

See example generated artifact here:
wasmer-c-api.tar.gz

This was a wrong doc link, intended to be the runtime-c-api not for the runtime.

We are fixing it in this PR :)

1. Should we include the lib/runtime-c-api/doc/ directory? I think it should be great to offer offline documentation?
2. Should we rename libwasmer_runtime_c_api to libwasmer? I understand it is simpler and shorter, but it's less self-describing. Could it “block” us for future projects or distributed/shared libraries?

I tried, but is not trivial to do it (since it requires doxygen installed in all the distributions OR manage more artifacts between pipelines).
I think we can do it in a PR apart

I think we should keep it as simple as possible for now. libwasmer is a bit more aligned, since our header is named wasmer.h.

Happy to revisit this in the future though :)

looks pretty good! My primary concern is that make build-capi doesn't seem to build the capi 🤔
