Add Embedded Swift for Wasm support to install-and-build-with-sdk.sh

[MaxDesiatov]

Also cleaned up incorrect "SDK" naming: we're using Swift SDKs and not plain Clang or Xcode SDKs in these workflows.

Additionally "static SDK" is very non-specific, Swift SDKs for Wasm are also static, as we currently don't support dynamic linking on that platform. We should fully specify it as "Static Linux", same as in https://www.swift.org/documentation/articles/static-linux-getting-started.html

Thanks for fixing the SDK terminology and adding embedded support! Left some comments on logs that could also be updated from just "static SDK" but looks good.

Just to clarify, the _wasm-embedded SDK is included in the _wasm.artifactbundle.tar.gz that's installed, right? Also, do we want to add a job that tests the embedded build in swift_package_test.yml and pull_request.yml?

Yes.

Those will be changed in follow up PRs, as I don't see a way for a workflow change PR to refer to a script using absolute URL changed in the same PR. Before merging we need it to refer to main and PR branch is not main.

Looks great, thanks!
