Do not REQUEST_DATA_STREAMs by default, since it's deprecated

[TishSerg]

Proof: https://mavlink.io/en/messages/common.html#REQUEST_DATA_STREAM

Description

MavLink command REQUEST_DATA_STREAM is DEPRECATED: Replaced by MAV_CMD_SET_MESSAGE_INTERVAL. So, QGroundControl shouldn't use it by default.

Test Steps

1. Install QGroundControl on clean machine where it wasn't installed before or wipe QGroundControl saved settings.
2. Go to Application Settings, Telemetry, Stream Rates.
3. See default setting of "Controlled By vehicle" checkbox slider (when it's ON it means REQUEST_DATA_STREAM is disabled).
