enhance(main/mesa): Freedreno KGSL & Turnip for mesa 26.3.0-devel-20260824

[lfdevs]

• Based on Robert Kirkman's PR ([not for merging] enhance(main/mesa): Lucas Fryzek and xMeM's freedreno kgsl for mesa 25.1.1 termux/termux-packages#24840), rebased to mesa's newer devel version.
• Continuation of this draft PR: [not for merging] enhance(main/mesa): Lucas Fryzek and xMeM's freedreno kgsl & some patches for anland termux/termux-packages#30162
• For convenience and some potentially needed latest features, I directly specified the source code as a branch of my repository. This branch has already applied patches such as 0013-detect-sve-sve2-support.patch, 0016-unofficial_support_adreno_710_720_722.patch, 0017-preserve-egl-support-in-zink.patch, 0018-disable-general-layout-in-zink-for-turnip.patch, etc., so the already applied patches are not repeatedly used here.
• The original inventor of this code is Lucas Fryzek. The Termux:X11 port of this code was created by xMeM.
• Requires specifying the environment variable MESA_LOADER_DRIVER_OVERRIDE=kgsl when used.
• Current version of this PR is 26.3.0-devel-20260824. For detailed changelog, please see the release notes on https://github.com/lfdevs/mesa-for-android-container/releases.

Tip

• Due to current limitations, if you use desktop environments such as Xfce 4 or KDE Plasma, please disable the display compositor first before installing the build artifacts of this PR.
• If screen tearing issues occur when running certain programs or games, you can add the following two environment variables to force-enable vertical sync:

  vblank_mode=3 MESA_VK_WSI_PRESENT_MODE=mailbox
