Register bindings for new device interfaces

[PeterBowman]

Follow-up of #2978 and #2993. Successfully tested on Python and the corresponding fake device implementations. Incidentally, the new headers have been also added to <yarp/dev/all.h>.

Sample usage:

import yarp

options = yarp.Property()
options.put('device', 'fakeLLMDevice')

dd = yarp.PolyDriver(options)
llm = dd.viewILLM()

llm.setPrompt('test')

vs = yarp.SVector(1)
vsp = yarp.SPairVector()

llm.readPrompt(vs) # `vs[0]` yields 'test'
llm.ask('blah blah blah', vs)

llm.getConversation(vsp)
# `vsp[0]` yields ('system', 'test')
# `vsp[1]` yields ('user', 'blah blah blah')
# `vsp[2]` yields ('assistant', 'Fatti non foste per viver come bruti ma per seguir virtute e canoscenza')

llm.deleteConversation()
