Adds SASLOAuthBearer flow to AIO Kafka's Faststream Security Parsing

[sifex]

Description

This PR adds SASLOAuthBearer flow to the AIOKafka driver to match the Confluent implementation as closely as possible.

Reference:
https://faststream.airt.ai/latest/confluent/security/#4-sasloauthbearer-object-with-ssltls

Basic implimentation would look like:

import ssl

from faststream.kafka import KafkaBroker
from faststream.security import SASLOAuthBearer

ssl_context = ssl.create_default_context()
security = SASLOAuthBearer(
    use_ssl=True,
    ssl_context=ssl_context
)

broker = KafkaBroker(
    "localhost:9092",
    security=security,
    sasl_oauth_token_provider=...
)

where sasl_oauth_token_provider is an instance of a class that implements AbstractTokenProvider.
