mesa-vpu: drop Hook 1 (overlay) and Hook 3 (browser) — now covered by armbian-config

Two hooks in extensions/mesa-vpu.sh are now redundant with
armbian-config's module_desktops:

  * extension_prepare_config__3d — appended panthor-gpu to
    DEFAULT_OVERLAYS on rockchip-rk3588 / rk35xx + BRANCH=vendor.
    module_desktops now enables the same overlay via
    _module_desktops_add_3d_overlay (configng commit 8248b497),
    which delegates to the existing module_devicetree_overlays
    install path — atomic armbianEnv.txt rewrite, .bak preserved,
    validates against the discovered .dtbo set, idempotent. Same
    gating (BOARDFAMILY + BRANCH + release + tier + DE) enforced
    on the configng side. Covers both image-build
    (module_desktops install mode=build) and install-on-minimal
    (runtime armbian-config invocation).

  * post_armbian_repo_customize_image__browser — installed a
    browser (google-chrome-stable on amd64, chromium on arm64 /
    armhf, firefox elsewhere) via chroot_sdcard_apt_get_install
    AFTER module_desktops had already placed our branded
    chromium conffiles. That second apt run — without
    --force-confdef --force-confold — tripped dpkg's 'File on
    system created by you or by a script' prompt on our
    /etc/chromium/master_preferences. The hook is also
    architecturally duplicated: configng's common.yaml 'browser'
    virtual token resolves to the correct package per
    (release, arch), more correctly than this hook (this fallback
    used plain 'firefox' which only exists on Ubuntu — Debian
    riscv64 needs firefox-esr; Ubuntu riscv64 needs
    epiphany-browser; configng handles both). Drop the hook.

The remaining hook (post_install_kernel_debs__3d) stays — it
carries genuine build-framework-only responsibilities: the
rk3588-specific rockchip-multimedia PPA + its packages
(rockchip-multimedia-config / libv4l-rkmpp / gstreamer1.0-rockchip /
libwidevinecdm0), the KDE Neon base-files / libdav1d7 holds, and
the final dist-upgrade pass. Those all gate on board / kernel /
release combinations that configng (which only knows release ×
arch, not LINUXFAMILY × BRANCH) can't express today.
