macOS: Replace deprecated CVDisplayLink calls in main and apple subproject

[SRSaunders]

Fixes #1287.

This PR does the following:

1. Updates the main project's vulkanexamplebase to replace deprecated CVDisplayLink calls with CAMetalDisplayLink instead. This means the main project will compile and work on macOS 14 (Sonoma) and later. Sonoma is currently the oldest supported version of macOS (but will likely become unsupported this fall 2026).
2. Updates the apple subproject for macOS to replace deprecated CVDisplayLink calls with CADisplayLink instead. Again, This means the apple subproject will compile and work on macOS 14 (Sonoma) and later. The iOS portion of the subproject has already been using CADisplayLink for some time so that portion does not change.
3. Updates the apple subproject to replace the deprecated setFrameInterval function with setPreferredFrameRateRange
4. Updates the apple subproject for macOS to implement the viewDidAppear entry point to mirror the iOS code.
5. Updates the apple subproject to include dynamicrenderinglocalread and descriptorheapuntyped in examples.h

Tested on macOS Sequoia 15.7.9 on x86_64, a real iPhone 16 (iOS 26.6), and the iOS Simulator on x86_64 (iOS 26.2).

Tested on macOS 26.6 on Apple Silicon (M1 Air) with both MoltenVK and KosmicKrisp drivers (SDK 1.4.357).
