module: do less CJS module loader initialization at run time

This patch:

• Builds the set of modules that can be required by users with/without the node: prefix at snapshot building time. We only modify it when --expose-internals or the flag for experimental wasi module is true but the default set is now in the snapshot. At run time the CJS module loader only creates a frozen array out of it.
• BuiltinModule.canBeRequiredWithoutScheme() is now enough to determine if an id can be required without node: without an additional call to BuiltinModule.canBeRequiredByUsers()
• Replace the pending-to-deprecate methods on Module with an internal implementation that only queries the CLI flags when being invoked. So we can install these methods in the snapshot.
