Allow setting supports_embedded_runtimes crosstool capability using feature 

`supports_embedded_runtimes` can now be expressed using 'static_link_cpp_runtimes' feature (should be enabled for it to take effect).

This cl allows toolchain owners to express that toolchain supports embedded runtimes in the same way as other crosstool capabilities are expressed.

This cl is a step towards https://github.com/bazelbuild/bazel/issues/5883. Also
see the rollout doc here:
https://docs.google.com/document/d/1uv4c1zag6KvdI31qdx8C6jiTognXPQrxgsUpVefm9fM/edit#.

Flag removing legacy behavior is https://github.com/bazelbuild/bazel/issues/6861
