PyAPI: support building with the up-coming Python 3.12 - Account for new member in _PyArg_Parser. - Many Python op-codes have been removed. For the moment these are disabled in is_opcode_secure. Some should be added back as intrinsics, noted in code-comments.

Build: resolve errors & deprecation warnings with Python 3.14 beta Python 3.14 has moved some functionality into the public API, use the updated names even with older Python versions. Also resolve an error caused by variable reuse with delayed annotation evaluation for TextureProperties_MixIn on startup. Resolve #140695.

Refactor: Make header files more clangd and clang-tidy friendly When using clangd or running clang-tidy on headers there are currently many errors. These are noisy in IDEs, make auto fixes impossible, and break features like code completion, refactoring and navigation. This makes source/blender headers work by themselves, which is generally the goal anyway. But #includes and forward declarations were often incomplete. * Add #includes and forward declarations * Add IWYU pragma: export in a few places * Remove some unused #includes (but there are many more) * Tweak ShaderCreateInfo macros to work better with clangd Some types of headers still have errors, these could be fixed or worked around with more investigation. Mostly preprocessor template headers like NOD_static_types.h. Note that that disabling WITH_UNITY_BUILD is required for clangd to work properly, otherwise compile_commands.json does not contain the information for the relevant source files.

PyAPI: support Python 3.13 - `_PySet_NextEntry` has been removed, use generic iterator access which will has some additional overhead as it needs to create an iterator to access the values. - Add v3.13 compatibility defines to account for renaming: _PyObject_LookupAttr -> PyObject_GetOptionalAttr _PyLong_AsInt -> PyLong_AsInt - Unfortunately use of Python's internal API needs to be used to inspect op-codes in `bpy_driver.cc`. Testing GLTF/FBX IO there isn't any significant performance impact from these changes. Resolves #123871.
