Web Inspector: implement CompilerSourceMappingProvider.

CompilerSourceMappingProvider implements a cross-domain communication channel for loading source mappings and source files.
Front-end page can't send XHRs to source mapping server directly due to SOP restrictions. Instead, we inject an invisible iframe that is loaded from source mapping server and use window.postMessage to communicate with it.
iframe has a different origin and thus doesn't have access to front-end window.
