Qualcomm AI Engine Direct - Requantization Mechanism Implementation (#2823)

Summary:
- Implement requantization so mix quantization ( e.g., 8bit quant + 16 bit quant) can be properly delegated to QNN.
- Reusing test_qnn_backend_view_permute_matmul unit test to check mix quantization is working as expected.
- Added etdump logic back to qnn_executor_runner that was deleted unintentionally during this PR: https://github.com/pytorch/executorch/commit/a531ca5a5ab5b5e503739a40a7cbec2e46767f0b#diff-f3647de74042ac9a417e2d4000a6f2db00c22c89fd028e9433d3c79ffb7d56f6
- Refactor common arguments in VIT.
