Changed name and qnn_executor different path

[RemonComputer]

📚 The doc issue

I was following this tutorial

and I noticed that the compiled model deeplab file is ./deeplab/dl3_qnn_q8.pte instead of deeplab_v3/dlv3_qnn.pte
and the current qnn executor executable is build-x86/examples/qualcomm/executor_runner/qnn_executor_runner instead of build-x86/examples/qualcomm/qnn_executor_runner

Suggest a potential alternative/fix

I suggest that:

1. Change the compiled model name path to ./deeplab_v3/dlv3_qnn.pte
2. Change the qnn executable path to build-x86/examples/qualcomm/executor_runner/qnn_executor_runner

@cccclai Can you take a look? Sounds like a simple docs fix.
