Pull request overview

This pull request exposes additional option setter and getter methods in the C API for the NCNN library, enabling more fine-grained control over inference options. The changes include adding getter methods for 14 existing option flags and reorganizing the C API header for better readability. Additionally, the Python bindings are updated to expose the use_bf16_packed option.

• Added getter and setter functions for 14 option flags in the C API (use_local_pool_allocator, use_winograd_convolution, use_sgemm_convolution, use_packing_layout, various fp16/int8/bf16 options, use_shader_local_memory, use_cooperative_matrix)
• Reorganized C API header to group getters and setters together
• Added comprehensive C API tests for all new getter/setter functions
• Exposed use_bf16_packed option in Python bindings with corresponding tests
