Fix TOSA related breakages

[sdasgup3]

Hi @Tai78641

The recent TOSA dialect changes introduced by https://github.com/llvm/llvm-project/pull/129720 have caused breakages, for example:

/usr/local/google/home/sdasgup/Github/stablehlo/stablehlo/conversions/tosa/transforms/TosaRescaleLegalizeToStablehlo.cpp:68:25: error: no member named 'getRoundingMode' in 'mlir::tosa::RescaleOp'                
  bool doubleRound = op.getRoundingMode() == "DOUBLE_ROUND";                                                                                                                                                       
                     ~~ ^                                                                                                                                                                                          
/usr/local/google/home/sdasgup/Github/stablehlo/stablehlo/conversions/tosa/transforms/TosaRescaleLegalizeToStablehlo.cpp:110:9: error: no viable conversion from '::llvm::ArrayRef<int32_t>' (aka 'ArrayRef<int>') 
to 'Value'                                                                                                                                                                                                         
  Value multiplier = op.getMultiplier();   

The PR is an attempt to address some of these issues, but it appears that the problem is more involving than we initially anticipated. Do you mind helping us updating the StablehloQuantLegalizeToTosaRescale.cpp and TosaRescaleLegalizeToStablehlo.cpp passes to accommodate these recent changes.

#2752 disables certain build and test target to unblock integration while the while issue is fixed.

AI (@sdasgup3 ): Make sure to enable those targets once the current issue is resolved.

I already have a fix for the compile errors, and adjusted the tests legalize_quant_ops_to_tosa_rescale.mlir and legalize_tosa_rescale_to_stablehlo.mlir
The other disabled tests are still failing and will need adjustments.

I pushed a PR: #2756
that fixes the code and tests for the recent tosa dialect updates for TOSA Spec 1.0
note that this includes fixes for rescale zero points changes from attributes to operands in
llvm/llvm-project#130340 that has been merged into llvm but that has not been
pulled into stablehlo's llvm-project integration.

once the stablehlo llvm has been updated to include that, I will test and re-enable tosa legalization in stablehlo

@Tai78641

Thanks again for your fixes!

once the stablehlo llvm has been updated to include that, I will test and re-enable tosa legalization in stablehlo

#2758 is an attempt to test all the affected tests (including nullary.mlir,binary.mlir, and ternay.mlir) after updating the llvm.

This seems working fine and hence closing the ticket. Please feel free to re-open in case there is more to it.
