New issue by xlibun on void-packages repository

https://github.com/void-linux/void-packages/issues/49229

Description:
### Is this a new report?

Yes

### System Info

Void 6.6.21_1 x86_64 AuthenticAMD uptodate rrmFFFF

### Package(s) Affected

mesa-24.0.2_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/merge_requests/18158
https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/issues/1702

### Expected behaviour

HEVC, VP9, H264, AV1 HW acceleration available at all times

Kind of like this:
`vainfo: Supported profile and entrypoints
      VAProfileH264ConstrainedBaseline:	VAEntrypointVLD
      VAProfileH264ConstrainedBaseline:	VAEntrypointEncSlice
      VAProfileH264Main               :	VAEntrypointVLD
      VAProfileH264Main               :	VAEntrypointEncSlice
      VAProfileH264High               :	VAEntrypointVLD
      VAProfileH264High               :	VAEntrypointEncSlice
      VAProfileHEVCMain               :	VAEntrypointVLD
      VAProfileHEVCMain               :	VAEntrypointEncSlice
      VAProfileHEVCMain10             :	VAEntrypointVLD
      VAProfileHEVCMain10             :	VAEntrypointEncSlice
      VAProfileJPEGBaseline           :	VAEntrypointVLD
      VAProfileVP9Profile0            :	VAEntrypointVLD
      VAProfileVP9Profile2            :	VAEntrypointVLD
      VAProfileAV1Profile0            :	VAEntrypointVLD
      VAProfileAV1Profile0            :	VAEntrypointEncSlice
      VAProfileNone                   :	VAEntrypointVideoProc
`

### Actual behaviour

AV1 and VP9 acceleration missing, despite working before the update.

`vainfo: Supported profile and entrypoints
      VAProfileH264ConstrainedBaseline: VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointEncSlice
      VAProfileH264High               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointEncSlice
      VAProfileHEVCMain               : VAEntrypointVLD
      VAProfileHEVCMain               : VAEntrypointEncSlice
      VAProfileHEVCMain10             : VAEntrypointVLD
      VAProfileHEVCMain10             : VAEntrypointEncSlice
      VAProfileJPEGBaseline           : VAEntrypointVLD
      VAProfileNone                   : VAEntrypointVideoProc`

### Steps to reproduce

1. Update `mesa` packages
2. Launch `mpv` with `--hwdec=auto` or Firefox
3. No HW acceleration for VP9 and AV1 present
