encoding/ianaindex: add ASCII, document Index.Encoding

Index.Encoding returns a nil Encoding in case the charset is valid but
unsupported by the library. Document this behavior.

Because of this, US-ASCII is seen as unsupported.
Register it as a regular encoding. The decoder replaces non-ASCII bytes
with the unicode replacement character. The encoder returns a
RepertoireError when a non-ASCII rune is encountered.

Fixes golang/go#19421
