Split access model between components and resources #7255
Description
Yes it would under this access model. We could split this between "read all components" and "reads all resources" but I'm not sure how that would interact with the bitsets. Happy to try to do this in this PR, or defer it until later.

Currently reads_all and writes_all would access all resource and component data. This is not ideal, as EntityMut and EntityRef are much more useful if they can be accessed at the same time as resources.
