fix(useFocusVisible): use Reflect.defineProperty to wrap HTMLElement.prototype.focus

[antododo]

Closes #9649

✅ Pull Request Checklist:

• Included link to corresponding React Spectrum GitHub Issue.
• Added/updated unit tests and storybook for this change (for new code or code which already has tests).
• Filled out test instructions.
• Updated documentation (if it already exists for this component).
• Looked at the Accessibility Practices for this feature - Aria Practices

📝 Test Instructions:

1. yarn jest packages/react-aria/test/interactions/useFocusVisible.test.js — all 18 tests pass, including the new regression test does not throw when HTMLElement.prototype.focus is an accessor-only property.
2. Confirm the regression: temporarily revert just the src/ change, keep the new test, and rerun the command above. The new test should fail with TypeError: Cannot set property focus of [object HTMLElement] which has only a getter. Re-apply the src/ change and the test passes.
3. Smoke-test the wider interactions suite to confirm no regression: yarn jest packages/react-aria/test/interactions/ — all 237 tests pass.
4. In a real browser, nothing should change — focus rings, keyboard vs. pointer modality, and screen-reader virtual focus detection behave identically (the Reflect.defineProperty call is equivalent to the previous assignment against the default HTMLElement.prototype.focus data descriptor).

At this point, why override at all instead of using an apply trap?

@nwidynski The bug is the install mechanism (getter-only focus accessor breaks plain assignment), not the wrapper shape, so a Proxy would still need the same defineProperty + try/catch. Happy to switch if you see a concrete benefit.

@antododo Not with a Proxy, but via Reflect API. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Reflect/defineProperty

That wont throw when failing to install the override.

@nwidynski thanks for the suggestion, PR updated.

I'm fine with this, hopefully userEvent gets their act together soon
