docs/filters: add documentation to all existing OpenCL filters
---
Hi! Sorry for delay.
Added general instruction for format conversion in the start of overall section
and separatly for overlay_opencl.
As far as I understand, different format conversion depends on which formats
are supported

Add lumakey_opencl filter. Behaves like existing lumakey filter.

Hi!
Changed title to a proper one.
Thanks!

I am going to add it during the next week, thanks!
Add documentation to all existing OpenCL filters, except tonemap filter.
---
Creation of the seperate section for OpenCL filters is motivated by developing
support for Vulkan and CUDA and it is easier to show the capabilities of each
platform by adding new sections.

The very last clFinish() should be ok.

Hi!
I like your idea with OCL_FAIL_ON_ERR(), but still do not know which one is
better.
My idea relies on fact, that there are only few OpenCL functions which are used
multiple times in filters:
clSetKernelArg, clCreateKernel(in case when there are multiple kernels) and
maybe

Hi there!
Thank you for advices, I have fixed the problem when per plane matrices
application was incorrect. Now it works as expected and behaves like the
existing vf_convolution filter.
Tested for yuv and nv12 formats.
The following filters from ffmpeg documentation
Behaves like the existing convolution filter, except working on OpenCL
hardware frames.
Takes exactly the same options: 4 convolution matrices, 4 rdiv values, 4 bias
values.
If not specified, default parameters are applied.
Matrices can be different sizes.
NEW IN THIS PATCH:
-fixed bug, if

filter applies:
matrix0, rdiv0, bias0

Hi there. Thank you for your advices. I implemented 4 matrix / 4 rdiv / 4 bias
option for each plane of image, fixed mem-leaks, added error messages if the
matrix is invalid.

Hi there. Thank you for your advices.
I implemented 4 matrix / 4 rdiv / 4 bias support, fixed mem-leaks,
add error messages if matrix is incorrect, removed local kernel.
Kind regards. Danil
