refactor(compiler): split code paths for compile and bundle (#6304)

Browse source 
* 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)
