Fixes for instrumentation of IPP and OCL (#12637)

* fixed warning about re-declaring variable when both IPP and instrumentation are enabled

* fixed segfault when no funName provided

* compilation fixed when both OCL and instrumentation are enabled

* dnn(ocl4dnn): update kernel checks

* dnn: workaround for IDLF kernels on Intel iGPU

* dnn(test): remove "skip" check for unstable cases

* cmake: js cleanup

- avoid unnecessary 2 messages for other platforms
- drop MODULE_NAME variable

* js: cleanup build_js.py

* Remove isIntel check from deep learning layers

* Remove fp16->fp32 fallbacks where it's not necessary

* Fix Kernel::run to prevent localsize > globalsize

* Fix #12542

* Remove ignore of non-virtual-dtor error

- accepts script parameter (allows drag & drop from 'explorer')
- use script dir instead of current dir (can launch samples from 'samples/dnn')
- added 'pause' to show error messages (about missing numpy) instead of instant closing

- DNN: avoid very large models
- build filter per module
- fixed longTestFilter

- disabled due specific requirements (camera, OpenNI camera, etc)
- designed for manual validation
