* refactor "compile" and "runtimeCompile" in "compiler.ts" and factor out separate methods for "compile" and "bundle" operations * remove noisy debug output from "compiler.ts" * provide "Serialize" implementations for enums in "msg.rs" * rename "analyze_dependencies_and_references" to "pre_process_file" and move it to "tsc.rs" * refactor ModuleGraph to use more concrete types and properly annotate locations where errors occur * remove dead code from "file_fetcher.rs" - "SourceFile.types_url" is no longer needed, as type reference parsing is done in "ModuleGraph" * remove unneeded field "source_path" from ".meta" files stored for compiled source file (towards #6080)
