feat(core): allow to specify entry point for snapshotted ES modules (#17771)
This commit adds "ExtensionBuilder::esm_entry_point()" function that
allows to specify which of the extension files should be treated as an
entry point. If the entry point is not provided all modules are loaded
and evaluated, but if it is provided then only the entry point is explicitly
loaded and evaluated.
