add allow_all and deny_all methods to DynamicSceneBuilder

[atornity]

Objective

It would be convenient to be able to quickly deny or allow all components and resources on a DynamicSceneBuilder with a single method call.

Context: #15210 renamed {allow/deny}_all to {allow/deny}_all_components.

Solution

Added two new methods to DynamicSceneBuilder, allow_all and deny_all, which affect both the component and resource filters.

Showcase

Before

let builder = DynamicSceneBuilder::from_world(world)
    .deny_all_components()
    .deny_all_resources();

After

let builder = DynamicSceneBuilder::from_world(world).deny_all();

Doesn't this mean that the preexisting allow_all and deny_all calls by the users will have different semantics now? That should probably be mentioned in the migration guide.

Agreed; I'll update the migration guide of the linked PR.
