linux dynamic load libva (#10171)

1. Linux dynamic load libva, which can fix lack of libva dependency for
   appimage or flatpak, also fix libva version mismatch between build
and run.
2. Remove libvdpau, it's not used, and add libva2 explicitly for deb and
   appimage
3. Print FFmpeg configure log to know the actual codecs.

Test
*  ubuntu 22.04 x64
  - [x] deb
  - [x] flatpak
  - [x] appimage
* ubuntu 18.04
  * deb: fcntl64 not found
  - [x]:appimage
  - [ ]: platpak
hwcodec example:
  - [x]: combination of lacking any of libva2, libva-x11-2, libva-drm2,
    intel-media-va-driver
- [ ] federa
- [ ] arch
- [ ] arm64: my ci can't finish arm64 building
