LibJS+LibWeb: Add C++ compile_parsed_module wrapper

Browse Source 
Add compile_parsed_module() to RustIntegration, which takes a
RustParsedProgram and a SourceCode (from parse_program with
ProgramType::Module) and compiles it on the main thread with GC
interaction.

Rewrite compile_module() to use the new split functions internally.

Add SourceTextModule::parse_from_pre_parsed() and
JavaScriptModuleScript::create_from_pre_parsed() to allow creating
module scripts from a pre-parsed RustParsedProgram.

This prepares the infrastructure for off-thread module parsing.
