Subject: [ffmpeg] Add NVIDIA Codec feature for Windows and Linux (#9171)

* Add NVIDIA Codec support for Windows, Linux and Linux for Tegra

* [ffnvcodec] Fix typos, add/remove comments

* Bump nvcodec version to 9.1.23.1

* Update version number as per change request

* Use PORT variable instead of hardcoded portname

* Identify the release the hash pertains to

* Find nvcodec in 'installed' instead of 'packages'

* Force FFmpeg to look for nvcodec headers in the installed directory instead of /usr/lib/pkgconfig.

* Use p option on cygpath to convert full path in case it contains more than one entry
