Moves allocation of the WasmModuleObject for asm.js code out of SyncCompileTranslatedAsmJS
since that is called when we are compiling the native context independent SharedFunctionInfo
and the WasmModuleObject requires a native context. Instead save the members required to
create the object in the AsmWasmData and create it during module instantiation. Note:
since the Wasm module is an implementation detail for asm_wasm code and isn't exposed,
this doeesn't have semantic change for asm.js code.
As part of this change, the AsmWasmData is changed from a FixedArray to a dedicated
struct. Some logic is also moved from module-compiler to wasm-engine to make the
seperation between Wasm SyncCompile and AsmJS SyncCompile more clear.

BuildClassBoilerplate accessed the native context to get the
class_function_descriptors. Baseline compilation should be native context
independent, so we shouldn't access the native context at all. As it happens,
class_function_descriptors wasn't used so can just be removed.

Adds support for enqueuing parallel parse / compile tasks for eagerly
compiled IIFEs during parsing. If the --parallel-compile-tasks flag is
enabled, the parser will pre-parse eager top-level IIFEs and enqueue a
task on the compiler dispatcher to do the actual parsing / compilation
on a worker thread.
Currently we always enqueue the task, but we likely want to only
enqueue parallel tasks where the script has multiple IIFEs or a
substantial amount of top-level script code before the IIFE to avoid
the main thread having to immediately block on the parallel task. This
work will be done as a follow-up.
