refactor(react-router): Link component composeHandler performance (#5168)

I noticed a slight performance dip during some navigations and the
bottom-up call list of the flame graph seemed to point to the
`composeHandler`. This seems (surprising and) pretty minor, but I'm
measuring a consistent 3ms self-time when the resulting handler is
actually being called.

This PR proposes ditching array methods and using a `for-of` loop. This
is good-enough™ and preserves the generality and DX of this function for
a 25% perf improvement.

```sh
 ✓  @tanstack/react-router  tests/foo.bench.tsx > composeHandlers 10064ms
     name                      hz     min     max    mean     p75     p99    p995    p999     rme   samples
   · array methods  37,152,711.10  0.0000  0.1624  0.0000  0.0000  0.0000  0.0000  0.0002  ±0.14%  18576357
   · for-of         47,029,751.81  0.0000  0.0236  0.0000  0.0000  0.0000  0.0000  0.0001  ±0.07%  23514876   fastest

 BENCH  Summary

   @tanstack/react-router  for-of - tests/foo.bench.tsx > composeHandlers
    1.27x faster than array methods
```

A slightly more performant (~30%) version would be to handle *exactly* 2
handlers instead of an arbitrary number (since `composeHandlers` is only
used w/ 2 callbacks) but this does affect the generality and DX of this
function.

## Summary by CodeRabbit

- **Refactor**
- Updated link event handling to short-circuit when an action is
prevented, maintaining existing behavior.
- Streamlined internal logic for handling user interactions with links
for improved efficiency.
- **Performance**
- Minor efficiency improvements in link interaction handling without
altering the public API or user-facing behavior.
