- drop U_egl-x11-sw-fix-partial-image-uploads.patch:
the code in the function saw further fixes later on in the 24.2
branch.

- integrated changes by Andreas Schwab
* enable glamor also for driver build
* update rust crates
+ syn 2.0.39
+ proc_macro2 1.0.86
* enable valgrind also on riscv64
* added libvdpau_gallium package for generic VDPAU state tracker
* switch from "swrast" to "softpipe,llvmpipe" drivers
* use "-Dllvm-orcjit=true" for riscv64 build
* added libgallium to Mesa-dri package

- re-disable llvm for non-driver build by switching from "swrast"
to "softpipe" for gallium drivers in that case
- make previous changelog a bit nicer
