* emit a custom section from impl_runtime_apis! This change emits a custom section from the impl_runtime_apis! proc macro. Each implemented API will result to emitting a link section `runtime_apis`. During linking all sections with this name will be concatenated and placed into the final wasm binary under the same name. * Introduce `runtime_version` proc macro This macro takes an existing `RuntimeVersion` const declaration, parses it and emits the version information in form of a linking section. Ultimately such a linking section will result into a custom wasm section. * Parse custom wasm section for runtime version * Apply suggestions from code review Co-authored-by: David <dvdplm@gmail.com> * Fix sc-executor integration tests * Nits Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com> * Refactor apis section deserialization * Fix version decoding * Reuse uncompressed value for CallInWasm * Log on decompression error * Simplify if * Reexport proc-macro from sp_version * Merge ReadRuntimeVersionExt * Export `read_embedded_version` * Fix test * Simplify searching for custom section Co-authored-by: David <dvdplm@gmail.com> Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com>
