Remove default arguments before calling to __torch_dispatch__ (#61123)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/61123
This applies the design pattern of removing explicit arguments when they
coincide with the default arguments. This simplifies argument patterns
that dispatch kernels receive and make it easier for us to maintain BC
(as addition of a new default argument isn't immediately BC-breaking
for dispatch implementors).
There is an important extra API which I haven't implemented here yet,
which is to take an incomplete sequence of arguments and fill out their
defaults (in case the user did want normalization). I plan on adding
that in a future PR.
