`exported_program.run_decompositions(decomposition_table)` will optionally take a decomposition table, and run decompositions on the exported program, returning a new exported program. By default we will run the Core ATen decomposition table.
Splitting up this diff with the following one (D49742989) to make migrating Executorch easier:
1. Land this diff
1. Wait for a pytorch nightly to include this diff
1. Update executorch's pytorch nightly
1. Land the following diff to have export() return no decomps
Test Plan: Tested in following diff

Summary:
X-link: https://github.com/pytorch/executorch/pull/359
When exporting using enable_aot (through the torch.export path), we want to lift all constant tensors as buffers to the exported program. The ScalarToTensor pass in EXIR's aten_to_edge passes will create some constant tensors in the graph, so we will need to run a lift_constant_tensors pass afterwards.
Note that this only needs to be applied when exporting using the torch.export path because in the original path, nothing is lifted.
