Add option to suppress color in mqtt log_topic messages

[barcar]

Describe the problem you have/What new integration you would like

I would like to have an option to suppress the ANSI color codes from the MQTT messages emitted when log_topic is configured.

Something like the last 3 lines of this YAML snippet:

mqtt:
  broker: !secret mqtt_broker
  username: !secret mqtt_username
  password: !secret mqtt_password
  id: ${mqtt_client}
  topic_prefix: "esphome/${name}"
  discovery_prefix: ${topic_prefix}_discovery
  discovery: false
  log_topic: 
    topic: ${topic_prefix}/${name}/log
    include_color: false

Please describe your use case for this integration and alternatives you've tried:

MQTT log messages contain the ANSI color codes which makes them difficult to read. For example:

�[0;33m[W][component:238]: Components should block for at most 30 ms.�[0m

I would prefer them to be simply:

[W][component:238]: Components should block for at most 30 ms.

There do not seem to be any ways to pre-process these messages before they are sent.

Additional context

Nothing to add.
