Merge pull request #20536 from hedgepigdaniel:fix/ocl-context-create-ownership 
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

Merge pull request #20287 from hanliutong:dev-rvv-0.10 
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.

* Remove setvl.

* Remove useless initialization.

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