* Utilize GPUMemoryManager/Allocator for preallocation of intermediate tensor buffer memory.

* Formatting.

* Merge with master required rework of memory due to CFE pass. Moved function memory pool allocation to pass as a result.

* Formatting.

* Added pass source files.

* Updated tests to account for new assert check. All GPUAllocators should be deconstructed before allocation is made in GPUMemoryManager.

* GPUAllocator::close() can be used to close the allocator prior to destruction

* Removed open allocators. Replaced check with inspection of pass::MemoryManager node list.

* Formatting.

* Rename m_memory_buffers -> m_tensor_memory_buffers. Use full path to static alignment variable.

* FunctionMemoryReservation -> TensorMemoryReservation. Only return true in pass if reservation is made (bug fix).

* Moved static compilation mutex.

* Update external function with new pass name.

* GPU_ExternalFunction: Add s_memory_pool_alignment, remove optimize_and_assemble method.
