- dot with arbitrary number of inputs

Research direction
Start with the xarray top-level-functions reference linked in the issue and inspect PyTensor's existing top-level functions, including broadcast, concat, where, full_like, zeros_like, ones_like, and dot. Add cov, corr, and cross, extend dot for an arbitrary number of inputs, and add tests showing the missing functions and expanded dot behavior are supported.
