feat(win/nvenc): dynamic sdk version selection at runtime

[ns6089]

Description

Notes

• submodules moved from nv-codec-headers to nvenc-headers to avoid conflicts during branch switching
• 1202 tracks master because there is no branch for this version yet

Todo

• [x] update doxygen comments
• [x] add some automatic regression tests for older sdk's
