Mira ae2fcc0353 Resource hooks & immutable resources (#24164) ...

# Objective

Enables the resource derive macro to specify the attributes for
- hooks (fixes #24159)
- immutability (fixes #24166)

Also fixes `resource_scope` overwriting change ticks and a few related
doc comments.

## Showcase

```rust
#[derive(Resource)]
#[component(immutable)]
#[component(on_insert = update_level, on_discard = update_level)]
struct Level(i32);
```
