* Adds CPU-to-CUDA copy capability to
ggml_backend_cuda_cpy_tensor_async()
* Adds function to relax sync requirements between input copies on
supported backends (CUDA for now)
* Exchanges synchronous copy with async copy function.
* Adds macro guards to allow compilation in non-CUDA builds
* Reworked backend detection in ggml-backend.cpp to avoid linking
conflicts
* Relax requirement of checks in async CUDA copies from backend and buffer type to just buffer type, to avoid linking issues
* Minor cleanup
* Makes opt-in to relax use of explicit syncs more general. Backends like
vulkan which require a synchronization between HtoD copies and graph
execution could also adopt this change now.
* Reintroduces stricter check for CPU->CUDA backend async copy via
GGML_DEVICE_TYPE_CPU.
* Corrects initialization of ggml_backend_sync_mode in
ggml_backend_sched_split initialization
* Simplifies synchronizations to adhere to `saaasg` pattern.
* Apply suggestion from @ggerganov (src->buffer to buf_src)

* Refactor: Moves cuda graph executable update step to separate function.
* Refactor: Moves cuda graph update check to separate function.
* Refactor: Moves cuda graph maintenance (update or adjusting copy parameters) to separate function for improved readability.
* Fix: Adds missing reference to maintain_cuda_graph() definition.
* Refactor: Improves structure and abstractions by moving CUDA graph evaluation and capture to its own function.
* Refactor: Moves node graph checks and copy ops into individual function for improved readability.
* Refactor: Removes code permanently excluded from compilation to increase readability.
* Style: Adds missing newline
* Style: Consolidates several neighboring '#ifdef USE_CUDA_GRAPH' into a single one
* Refactor: Makes 'cuda_graph_update_required' a local variable
* remove double lines between functions

* Renames NVIDIA GPU-architecture flags to avoid name clashes with WinAPI. (e.g. CC_PASCAL, GPU architecture or WinAPI pascal compiler flag?)
* Reverts erroneous rename in SYCL-code.
* Renames GGML_CUDA_MIN_CC_DP4A to GGML_CUDA_CC_DP4A.
* Renames the rest of the compute capability macros for consistency.
