Failures/Errors in unit test (with QualComm's AI SDK)

🐛 Describe the bug

Hello,
I'm trying to compile and run some models for Executorch with QCOM backend, but I've bumped into various issues at build & execution time.

1. Here is the version info:
   Executorch: 0.2.1, 0.3.0 RC, 0.4.0 (main)
   QCOM AI Direct Engine SDK: 2.16, 2.23, 2.24

2. cd to /backends/qualcomm/tests/, and run the unit tests:
   python3 test_qnn_delegate.py -b ../../../build_android -m SM8550

3. As you can see from the attached screen shot, it has many failures. Actually I tried 3 different branches with recommended SDK versions..
   

Is this expected? If not, please help us identify our setup
