Skip View prop transforms when no transformed props are passed

[shubh73]

Summary:

View copies its props and runs about 15 checks on every render to map aria-*, id and tabIndex onto their native equivalents. Most Views set none of these, so this checks the 17 keys first and, if none is set, passes props straight to ViewNativeComponent. Views that set any of them take the existing path, unchanged.

The transforms stay in JS, where #56699 left them; this only skips them when there's nothing to transform. A new test fails if the keys needsPropTransforms checks drift from the ones transformProps reads.

Native props are unchanged. On device, I recorded every payload sent to createNode/cloneNodeWithNewProps, before and after, across 2,516 random mount/update steps: keys and values match in every step. In 3 updates, a removed key appears in a different position; native reads props by name, so this isn't observable.

Case	Before	After	Change
Mount, plain	507 µs	455 µs	-10.2%
Update, plain	527 µs	485 µs	-7.9%
Mount, testID + pointerEvents	599 µs	512 µs	-14.5%

Update, aria-label	553 µs	568 µs	+2.6%
Mount, accessibilityState	595 µs	603 µs	+1.4%

The existing View-vs-ViewNativeComponent benchmark goes from 527 µs to 468 µs (-11.2%).

Device (OPPO CPH2667, Dimensity 6300, RNTester release build, 500–600 Views, median of 3 × 100 runs)

Mount, plain	24.3 ms	23.2 ms	-4.6%
Update, plain	19.2 ms	18.3 ms	-5.0%
Mount, testID + pointerEvents + hitSlop	28.2 ms	26.2 ms	-6.9%
Update, testID + pointerEvents + hitSlop	21.1 ms	19.3 ms	-8.6%
Mount, list rows (6 nested Views)	30.8 ms	29.3 ms	-4.8%
Update, list rows (6 nested Views)	11.3 ms	10.5 ms	-6.4%
Mount, aria-label	25.5 ms	25.7 ms	+0.9%
Update, aria-label	19.9 ms	20.1 ms	+1.1%
Mount, accessibilityState + accessibilityValue	31.8 ms	32.1 ms	+1.1%
Update, accessibilityState + accessibilityValue	24.3 ms	24.3 ms	+0.3%

Device times are JS-thread time for the whole update, including commit and layout, so the relative change is smaller than in Fantom. That's 1.2–3.9 µs saved per View.

Changelog:

[GENERAL] [CHANGED] - Skip View prop transforms when no aria-*, id or tabIndex props are passed

Test Plan:

• yarn test packages/react-native: 5241 passed, including the new View-propTransforms-test.
• yarn fantom packages/react-native/Libraries/Components/View: 259 passed.
• yarn flow-check, ESLint, Prettier: clean.
• Differential Jest test against the previous View (not committed): ~25k prop combinations, comparing iOS and Android create and diff payloads. All match.
• On device: the payload recording above (APK from main vs. this branch), plus uiautomator dumps of RNTester's Accessibility and View examples. The same 617 accessibility nodes before and after.
