Shelley Vohr 9c641c590f module: cache nearest parent package.json per directory 
getNearestParentPackageJSON() memoized its answer per file, so every
module loaded still made one native call, and TraverseParent() builds
several std::filesystem::path temporaries per directory level and
serializes the whole package.json, which the JS side then usually
discarded because it already had that package.json deserialized.

The native traversal starts at the directory of the given path, so the
answer only depends on that directory: key the memo by it (following
NormalizePath()'s trailing-separator rule), so that all modules in a
directory share one native call. When the permission model is enabled
the traversal also depends on the read permissions in effect at call
time, so that configuration keeps the per-file cache.

Loading a 1000-module tree spread over ~240 directories goes from 1000
to 236 native calls.

Joyee Cheung 1d6a62662c src: move import.meta initializer to native land 
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.
