Introduce ThreadLocal Class + Fix Several GPU Bugs

* Fix `AddClearColorSubpass` bug where it would not generate a `VkCmdNextSubpass` when an attachment clear was utilized
* Fix `AddSubpass` bug where the Depth Stencil texture would not be synced
* Respect `VkCommandPool` external synchronization requirements by making it thread-local with a custom RAII wrapper
* Fix linear RT width calculation as it's provided in terms of bytes rather than format units
* Fix `AllocateStagingBuffer` bug where it would not supply `eTransferDst` as a usage flag
* Fix `AllocateMappedImage` where `VkMemoryPropertyFlags` were not respected resulting in non-`eHostVisible` memory being utilized
* Change feature requirement in `AndroidManifest.xml` to Vulkan 1.1 from OGL 3.1 as this was incorrect
