Vulkan: Fix Fuchsia external semaphore fix tryWait().

Fix an issue where tryWait() would abort when called on an unsignaled semaphore. Due to the fact that zx_object_wait_one() will return ZX_ERR_TIMED_OUT in this case (because the expiration time was set with zx_clock_get_monotonic() instead of ZX_TIME_INFINITE). This fixes an issue that appears when vkWaitForIdle() is called by certain Fuchsia Vulkan graphics tests. + Replace ABORT() calls with DABORT() and proper returns to avoid crashing if DCHECK_ALWAYS_ON is not defined at build time.
