* Configure MoltenVK to use a dedicated compute queue for compute[*] examples with sync barriers * Modify descriptorindexing example for iOS and variable descriptor count limitations on MoltenVK * 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 * Configure MoltenVK with a dedicated compute queue in VulkanExampleBase() and remove from samples
