* Remove obsolete macOS #ifdefs no longer needed for modern MoltenVK versions

* Update iOS project to fix missing vkloader.c reference and revise example list

* Set required features and API version for VVL in debugprintf example

* Remove unnecessary Apple-specific code from descriptorindexing example

* Add Layer Settings capability to VulkanExampleBase::createInstance()

* Replace setenv() in examples with Layer Settings configuration for macOS/iOS

* Update comments in examples.h and fix missing initializer in computeraytracing example

* Update imgui overlay and example to support iOS Simulator

* Update more comments in examples.h and remove redundant initializers in deferred* examples

* Separate variable descriptor count declarations for apple and non-apple platforms

* Consolidate variable descriptor count declarations for apple vs. non-apple platforms
