avfilter/vf_transpose_vulkan: add clock and cclock option 

The following command is on how to apply cclock option:

ffmpeg -init_hw_device vulkan -i input.264 -vf \
hwupload=extra_hw_frames=16,transpose_vulkan=dir=cclock,hwdownload,format=yuv420p \
output.264

The following command is on how to apply clock_flip option:

ffmpeg -init_hw_device vulkan -i input.264 -vf \
hwupload=extra_hw_frames=16,transpose_vulkan=dir=clock_flip,hwdownload,format=yuv420p \
output.264

The following command is on how to apply clock option:

ffmpeg -init_hw_device vulkan -i input.264 -vf \
hwupload=extra_hw_frames=16,transpose_vulkan=dir=clock,hwdownload,format=yuv420p \
output.264
