Remove unnecessary branch in query iteration

[re0312]

Objective

• Since Reduced TableRow as Casting #10811,Bevy uses assert in the hot path of iteration. The for_each method has an assert in the outer loop to help the compiler remove unnecessary branching in the internal loop.
• However , for style iterations do not receive the same treatment. it still have a branch check in the internal loop, which could potentially hurt performance.

Solution

• use TableRow::from_u32 instead of TableRow::from_usize to avoid unnecessary branch.

I'd actually suggest downgrading the assert in TableRow::from_usize to a debug_assert. Anything touching query iteration and storage shouldn't be panicking in a release build (see #12107 and #12149).

Can you also do this for TableId?
