This PR adds **Core** iOS support to the OpenUSD project. This does not include Imaging, and any Imaging related components at this time. Imaging will be added in a follow up PR. MaterialX is also disabled as requested and the upgrade will be handled in a follow up PR. It is a minimal version of PixarAnimationStudios#2455 against the latest `dev` branch. Changes include: * Using latest dev branch * No imaging support. Will be added in a follow up PR. * Makes use of CMake's inbuilt iOS support, negating the need for toolchain support * Structures the code in such a way that we can add support for other iOS derived platforms+simulator in future PRs * Swaps `ARCH_OS_IOS` with `ARCH_OS_IPHONE` to align with compiler directives. IPHONE refers to all derivative platforms, whereas iOS refers to only iPhone/iPad (Confusing but the case for historical reasons as [documented here](https://chaosinmotion.com/2021/08/02/things-to-remember-compiler-conditionals-for-macos-ios-etc/)) * TBB requires SDKROOT to be passed in or it can often go off and find some random compiler toolchain and fail. * Add APPLE_EMBEDDED boolean to designate when using the CMake supported cross compilation targets. Added in Options.cmake so it can be used to configure defaults properly.
This PR builds on the [Core iOS support PR](PixarAnimationStudios#2949) to add support for building the USD core for visionOS. Thanks to Valentin Roussellet for the basis of the TBB patch. It includes the following changes: * Use CMake 3.28 (which adds visionOS support) * Patch TBB to support visionOS. Note that clang requires new platforms to be provided via the target triplet. * Add visionOS to the accepted platforms. Note that visionOS's SDK is called xros, much like how the iOS SDK is iphoneos for historical reasons.
