When the source text module is compiled without custom callbacks,
instead of calling into JS land from the per-isolate import.meta
initializer and then back to C++ land to set up lazy data
properties, just do the initialization all in C++ land.
Only import.meta.resolve initialization will call back
into JS land to generate a closure that call the cascaded loader
for resolution.
In addition, simplify the loader structure by merging
allowImportMetaResolve into isForAsyncLoaderHookWorker - the two
are essentially equivalent, as import.meta.resolve is only
allowed in a non-loader-hook worker thread's loader.
