Preserve Aliased Functions in StableHLO Quantizer
Preserve Aliased Functions in StableHLO Quantizer

Aliased functions are represented as StatefulPartitionedCall in the TF graph. They will be marked tf._noinline=true so that Inliner pass will skip them. In this CL I:

* modified TF->StableHLO pass to skip lowering them to func.call op.
* modified ReplaceStablehloOpsInMainFunctionWithXlaCallModuleOpsPass. So that StableHLO graph in each StatefulPartitionedCall will be lifted.
