[G-API] Extend compileStreaming to support different overloads

* Make different overloads

* Order python compileStreaming overloads

* Fix compileStreaming bug

* Replace

gin -> descr_of

* Set error message

* Fix review comments

* Use macros for pyopencv_to GMetaArgs
* Use GAPI_PROP_RW
* Not split Prims python stuff

* Added exposure and gain props, maximized pixel clk

* removed pixel clock maximization

pixel clock maximization is not suitable for all use cases, so I removed it from PR.

fix ONNXImporter diagnostic mode layer registration issue

* fix layer registration, thread unsafe access and align the behavior of DNN_DIAGNOSTICS_RUN between onnx and tf importers

* move skipModelInput

* print all missing layers

* address TF issue

The two argument versions has been deprecated, cf
https://developers.google.com/protocol-buffers/docs/reference/cpp/google.protobuf.io.coded_stream

docs(core/ocl): clarify ownership of arguments passed into OpenCL related functions

* docs(core/ocl): clarify ownership in OpenCLExecutionContext::create

Although it is technically true that OpenCLExecutionContext::create
calls `clRetainContext` on its context argument, it is misleading
because it does not increase the reference count overall. Clarify that
the ownership of one reference of the passed context and device is
taken.

* docs(core/ocl): document ownership transfer in ocl::Device::fromHandle

Optimization of DNN using native RISC-V vector intrinsics.

* Use RVV to optimize fastGEMM (FP32) in DNN.

* Use RVV to optimize fastGEMM1T in DNN.

* Use RVV to optimize fastConv in DNN.

* Use RVV to optimize fastDepthwiseConv in DNN.

* Vectorize tails using vl.

* Use "vl" instead of scalar to handle small block in fastConv.

* Fix memory access out of bound in "fastGEMM1T".

* Remove setvl.

* Remove useless initialization.

* Use loop unrolling to handle tail part instead of switch.

* Add initialization and inference for GRU layer

* fix issues found on review
