RFR: 8356888: (fs) FileSystems.newFileSystem that take an env must specify IllegalArgumentException [v2]

[Brian Burkhalter]

> Add a throws clause for `IllegalArgumentException` to the `java.nio.file.FileSystems` methods `newFileSystem(Path, Map)` and `newFileSystem(Path, Map, ClassLoader)`. Also update the equivalent IAE verbiage for the analogous methods which accept a `URI` parameter instead of a `Path`.

Brian Burkhalter has updated the pull request incrementally with one additional commit since the last revision:

  8356888: Added @since 13 to newFileSystem(Path,C;assLoader)
