Remove .impl_UNBOXED() and functionalities associated with it

[smessmer]

Stack from ghstack:

• Remove backward and requires_grad from Autograd backend key #49613 Remove backward and requires_grad from Autograd backend key
• Remove use_c10_dispatcher: full lines #49259 Remove use_c10_dispatcher: full lines
• Remove generated_unboxing_wrappers and setManuallyBoxedKernel #49251 Remove generated_unboxing_wrappers and setManuallyBoxedKernel
• Remove .impl_UNBOXED() and functionalities associated with it #49220 Remove .impl_UNBOXED() and functionalities associated with it
• Remove codegen logic to support non-c10-full ops #49164 Remove codegen logic to support non-c10-full ops

Since all ops are c10-full, we can remove .impl_UNBOXED now.
This also removes the ability of KernelFunction or CppFunction to store unboxedOnly kernels.

Good riddance!!!

Guessing this will need an XLA companion?
