vulkan: Refactor vk_queue to use per-instance mutexes and unique handles (#23570)

Browse Source 
* Refactor vk_queue to use per-instance mutexes and unique handles

* integrates VK_KHR_internally_synchronized_queues, abstracting the queue submission into a polymorphic interface that completely bypasses host-side mutex locking when driver-side synchronization is supported

* fix compilation error

* fix duplicate pNext chain for VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR

* add fallback defines for VK_KHR_internally_synchronized_queues

* add null checks for queues in vk_device_struct destructor

* use unique_ptr for outer queues to enforce exclusive ownership and optimize lifetime

* use static constexpr for eInternallySynchronizedKHR

* add lock guard to ggml_vk_create_aliased_queue for thread safety

* initialize sync_query_features.internallySynchronizedQueues to VK_FALSE

* reuse sync_query_features for internallySynchronizedQueues and simplify chaining

* refactor internallySynchronizedQueues detection

* fix internallySynchronizedQueues query guard

* use eInternallySynchronizedKHR constant

* fix self-referential alias for eInternallySynchronizedKHR

* use macro for eInternallySynchronizedKHR fallback

* fix internallySynchronizedQueues query timing in ggml-vulkan.cpp to prevent device creation mismatch

* reset sync_query_features.pNext before reusing in device creation chain, also removed the redundant second probe call

* refactor internally synchronized queues detection to use chained feature query and avoid redundant API calls

* Update ggml/src/ggml-vulkan/ggml-vulkan.cpp

Co-authored-by: Jeff Bolz <jbolz@nvidia.com>

* rename sync_enable_features to internally_synchronized_queues_features

* queue_flags is still computed before has_internally_synchronized_queues is set

* fix trailing whitespace

* replace eInternallySynchronizedKHR macro with static constexpr

* preserve source queue semantics in single-queue aliased transfer queue

* vulkan: fix cmd_pool access via pointer for compute_queue unique_ptr

* vulkan: lock queue during debug label emission when not internally synchronized
