libcamera: Use stream roles directly instead of StreamUsage

In order to prepare for an API overhall of the camera configuration
generation, remove the StreamUsage class and replace its uses by stream
roles. The size hints can't be specified anymore, and will be replaced
with an API on the StreamConfiguration to negotiate configuration
parameters with cameras.
