temp/mesa-git: align with upstream APKBUILD (consolidate subpackages) (!896)

Included changes:

  - main/mesa: build freedreno only for arm
    https://gitlab.alpinelinux.org/alpine/aports/merge_requests/2809

  - tree-wide: use --buildtype=debugoptimized for meson packages
    https://gitlab.alpinelinux.org/alpine/aports/merge_requests/2619

  - main/mesa: consolidate subpackages
    https://gitlab.alpinelinux.org/alpine/aports/merge_requests/2816

  - main/mesa: use qualified provides for deprecated subpackages
    https://gitlab.alpinelinux.org/alpine/aports/merge_requests/3167
