Gemm kernels for Intel GPU (#8104)

* Fix an issue with Kernel object reset release when consecutive Kernel::run calls

Kernel::run launch OCL gpu kernels and set a event callback function
to decreate the ref count of UMat or remove UMat when the lauched workloads
are completed. However, for some OCL kernels requires multiple call of
Kernel::run function with some kernel parameter changes (e.g., input
and output buffer offset) to get the final computation result.
In the case, the current implementation requires unnecessary
synchronization and cleanupMat.

This fix requires the user to specify whether there will be more work or not.
If there is no remaining computation, the Kernel::run will reset the
kernel object

* GEMM kernel optimization for Intel GEN

The optimized kernels uses cl_intel_subgroups extension for better
performance.

Note: This optimized kernels will be part of ISAAC in a code generation
way under MIT license.

* Fix API compatibility error

This patch fixes a OCV API compatibility error. The error was reported
due to the interface changes of Kernel::run. To resolve the issue,
An overloaded function of Kernel::run is added. It take a flag indicating
whether there are more work to be done with the kernel object without
releasing resources related to it.

b1851e2f16 Add support to print cv::UMat.
Now a user can use `std::cout` to print an object of `cv::UMat` just like `cv::Mat`.

Instead of CL_DEVICE_EXTENSIONS in Querying OpenCLVersion, it should be CL_DEVICE_VERSION flag which needs to be passed to the function.

5e4dfb9546 Change the argument type to cl_platform_info.
Although both `cl_platform_info` and `cl_device_info` are defined as macro `cl_uint`, it needs to use `cl_platform_info` to get
the platform information.

4c7aa8645a ocl: validate arguments in KernelArgs constructor
- don't use undefined flag=0. It should be CONSTANT instead.
- don't allow 'UMat* m=NULL' argument (except LOCAL/CONSTANT flags).
  This case is not handled well to provide NULL __global pointers.
  It is better to use '-D' macro defines instead (at least for performance)

Fix typos in the documentation for AutoBuffer. (#8197)

* Allocate 1000 floats to match the documentation

Fix the documentation of `AutoBuffer`. By default, the following code
```.cpp
cv::AutoBuffer<float> m;
```` 
allocates only 264 floats. But the comment in the demonstration code says it allocates 1000 floats, which is 
not correct.

* fix typo in the comment.
