esm: fix hook mistypes and links to types

Prior to this commit, the custom loader hooks were:
* missing the Node.js API ref docs types
* missing the function signature from their sections
* linking directly to the specification (not customary)
* had an inconsistent non-nullable JSDoc promise return
* had JSDoc object properties that weren't alpha-sorted
* designated set of non-nullable types when single was fine

 The `getFormat` hook provides a way to define a custom method of determining how
 a URL should be interpreted. The `format` returned also affects what the
 acceptable forms of source values are for a module when parsing. This can be one
 of the following:
