Resize a port buffer to at least `size` bytes.

resized and the port is still connected to the same location. Plugins
MUST gracefully handle this situation.
This function is in the audio threading class.
The host MUST preserve the contents of the port buffer when resizing.
Plugins MAY resize a port many times in a single run callback. Hosts
SHOULD make this as inexpensive as possible.
