[Build] Add linker script optimization (pytorch#121975)

This PR adds a linker script optimization based on prioritized symbols that can be extracted from the profiles of popular workloads. The present linker script was generated to target ARM+CUDA and later can be extended if necessary. The reason we target ARM is shown below:

> PyTorch and other applications that access more than 24x 2MB code regions in quick succession can result in performance bottlenecks in the CPU front-end.  The link-time optimization improves executable code locality and improve performance. We recommend turning on the optimization always for PyTorch and other application that behaves similarly.
