Summary:
Hi there,

This commit adds QNN backend. Please check setup.md and README under `backends/qnn` for more details.

We add pybind dependency at the top level, because we guess you might need it in the near future. If it's not the case, please feel free to tell us. We'll move it under `backends/qnn`.

Below is some SoC model mapping:

- `SM8550` -> `Snapdragon 8 Gen 2`
- `SM8475` -> `Snapdragon 8 Gen 1+`
- `SM8450` -> `Snapdragon 8 Gen 1`

Please feel free to contact us if you find any problem.

Summary:
An implementation of a TOSA Partitioner and TOSA backend supporting a small list of operators in fp32 and int8/32. This includes a set of integer networks which will then compile to target Ethos-U NPU using the Vela compiler.

* A small set of test networks in fp32
* A subset of these supporting integer and compiling with Vela
* A test wrapper to register and test networks through the compile stack
  * A flow pt2 -> executorch -> tosa_flatbuffer.tosa file -> tosa_reference_model
  * A flow pt2 -> executorch -> tosa_flatbuffer.tosa file -> vela -> command_stream
* This work depends on a few different python modules
  * https://review.mlplatform.org/plugins/gitiles/tosa/serialization_lib/
  * https://review.mlplatform.org/plugins/gitiles/ml/ethos-u/ethos-u-vela/
* This work uses other projects for validation
  * https://review.mlplatform.org/plugins/gitiles/tosa/reference_model/
