Subject: [PATCH] doc: add tls.convertALPNProtocols(protocols, out)

Add convertALPNProtocols() to doc/api/tls.md, since the source code
actually exposes this method.

+* `protocols`: {string\[]|Buffer\[]|TypedArray\[]|DataView\[]|Buffer|
+  TypedArray|DataView}
+  An array of strings, `Buffer`s, `TypedArray`s, or `DataView`s, or a
+  single `Buffer`, `TypedArray`, or `DataView` containing the supported ALPN
+  protocols. `Buffer`s should have the format `[len][name][len][name]...`
+  e.g. `'\x08http/1.1\x08http/1.0'`, where the `len` byte is the length of the
+  next protocol name. Passing an array is usually much simpler, e.g.
+  `['http/1.1', 'http/1.0']`. Protocols earlier in the list have higher
+  preference than those later.
+* `out` {Object} A output variable supplied by users, in which the converted `protocols` result `out.ALPNProtocols`.
