Add platform markers for linux only extra_install_requires (#88826)

Fixes #88049

#85097 added new extra dependencies on `nvidia-*`. They are linux (GPU) only packages, but were not marked as such, causing issues installing pytorch 1.13 via Poetry (and possibly other tools that follow PyPI's metadata API) on non-Linux systems. This "fixes" the issue by adding the `; platform_system = 'Linux'` marker on these dependencies, but the main problem of different metadata for different wheels is a [somewhat larger issue](#88049 (comment)).

#85097 used `;` as a delimiter for splitting the different deps, but that is the delimiter used in markers, so I changed to split on `|`.
