What does "bump a new runtime version" mean? Could you please provide
more details?

I'm confused about the version number of libvpl and oneVPL-intel-gpu.

I looked at the implementation of `QSV_RUNTIME_VERSION_ATLEAST`, and
tried to print `mfxVersion` stored in `vpp->qsv`.
I can only get 2.10 which is the version of libvpl (2.10.1 actually)
on my system.

I've also looked at the build directory of oneVPL-intel-gpu on my
system, the compile commands defines following

    -DMEDIA_VERSION_STR="24.1.2" -DMFX_API_VERSION="2.10+"

Do you mean I should just use `QSV_RUNTIME_VERSION_ATLEAST(ver, 2,
10)` to check the runtime version?
Does this guarantee the underlying oneVPL-intel-gpu would be >= 24.1.1 then?
