Support for Text-to-Speech models

[adrianboguszewski]

Optimum Intel is a great tool that combines the convenience of HF API with the performance of OpenVINO. It helps build virtual assistants with one exception - Text-to-Speech pipelines. Hence, I'm requesting that support be added, which will help include speech generation in our AI Ref Kits promoting Optimum Intel and OpenVINO.

Example

from optimum.intel import pipeline

synthesizer = pipeline("text-to-speech", "suno/bark")

synthesizer("Look I am generating speech in three lines of code!")
