Make addmm meta kernel consistent with mm (#84960)
Change the names of the parameters in the `addmm` meta kernel to be more consistent with `mm`. Functionally, the only difference in behaviour should be that `addmm` meta kernel gets its options from the `input` tensor instead of from the `bias` parameter.
Fixes #84930
