SystemParamBuilder - Enable type inference of closure parameter when building dynamic systems (#14820) 
# Objective

When building a system from `SystemParamBuilder`s and defining the
system as a closure, the compiler should be able to infer the parameter
types from the builder types.

## Solution

Create methods for each arity that take an argument that implements both
`SystemParamFunction` as well as `FnMut(SystemParamItem<P>,...)`. The
explicit `FnMut` constraint will allow the compiler to infer the
necessary higher-ranked lifetimes along with the parameter types.

I wanted to show that this was possible, but I can't tell whether it's
worth the complexity. It requires a separate method for each arity,
which pollutes the docs a bit:
![SystemState build_system
docs](https://github.com/user-attachments/assets/5069b749-7ec7-47e3-a5e4-1a4c78129f78)

## Example

```rust
let system = (LocalBuilder(0u64), ParamBuilder::local::<u64>())
    .build_state(&mut world)
    .build_system(|a, b| *a + *b + 1);
```
