[iOS] [added] - add more iOS flags into AccessibilityInfo

[estevaolucas]

Summary

As a follow-up to this other PR #23839, it adds support for other, iOS only, flags into AccessibilityInfo.

Changelog

It adds these other 4 methods:

• isBoldTextEnabled()
• isGrayscaleEnabled()
• isInvertColorsEnabled()
• isReduceTransparencyEnabled()

P.S: Android implementation for those methods just return false (with Promise.resolve(false))

And the corresponding event listeners:

• boldTextChanged
• grayscaleChanged,
• invertColorsChanged,
• reduceTransparencyChanged

Test Plan

isBoldTextEnabled and isReduceTransparencyEnabled can be tested on iOS Simulator, by enabling the respective flags in Settings > General > Accessibility

For isInvertColorsEnabled and isReduceTransparencyEnabled only on iOS device. iOS Simulator's accessibility is just a subset of device's one. To test those two flags:

• Settings > General > Accessibility > Display Accommodations > Invert Colors > enable Smart Invert;
• Settings > General > Accessibility > Display Accommodations > Color Filters > enable Color Filters;
