Remove set_quantizer_ from native_functions.yaml (#49463)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49463
set_quantizer_ takes a ConstQuantizerPtr argument, which is neither supported by JIT nor by c10.
Also, it doesn't get dispatched (CPU and CUDA have the same implementation) and it is excluded from python bindings generation.
So there is no real reason why this needs to be in native_functions.yaml
Removing it unblocks the migration to c10-fullness since this is an op that would have been hard to migrate. See https://fb.quip.com/QRtJAin66lPN
