Extend fp16 support for Xtensa
* handle min/max expressions in strides calculations * more robust check for nested loops
…#7303) * [xtensa] added infrastructure code for running tests * moved google related calls to CL
* Remove unnecessary special-casing of vector-size in camera-pipe * Update camera_pipe_generator.cpp * Remove unnecessary special-casing of vector-size conv_layer
…body() (#7340) This removes a nice chunk of redundant code (and adds some corner cases that were missing from the Xtensa version).
Generate PACKVRNR for i16(i32(i48x) >> wild_i32)
Remove __restrict from print_assignment
* [xtensa] Added a new optimize rule to avoid int32->int64->int32 path for a saturated cast of widening shift right * [xtensa] Added tests for i32_sat(widening_shifts) to simd_op_checik_xtensa * xtensa shifts handle 32th shift for int32x word differently. Adjusted the tests and add a missing rule for the optimizer. * Commented on the constraints for the IVP_SRSN_2X32 instruction argument

This backports the branch for Xtensa codegen into main. Note that it deliberately ignores changes to apps/ (which had grown stale); those changes may or may not be backported at a later date.
Aside from simd_op_check_xtensa, there are few tests for the new codegen paths; the next step to remedy that will be updating the buildbots to add code coverage for the existing test suite to the extent that is possible via AOT only (since the Xtensa codegen does not support JIT).
