webkit2gtk3: Fix of 62 CVEs

  • Rebase to webkitgtk 2.54.0 (WebKitGTK Security Advisory WSA-2026-0006), aligning with the release RHEL 9 ships (webkit2gtk3-2.54.0-1.el9_8, RHSA-2026:69098).
  • Adopt the CentOS Stream 9 2.54.0 packaging patch set; skia-s390x.patch and mimalloc.patch are new there for 2.54.0, fix-eclipse.patch is from c9s 2.54.0-2 and reverts 317619@main, which aborts Eclipse/SWT applications on a RELEASE_ASSERT in initializeMainThread.
  • Drop fix-renderflexbox-typename.patch (was Patch17); the code it patched is gone on 2.54.0.
  • Build with gcc-toolset-14 (GCC 14) instead of gcc-toolset-12; GCC 12 cannot compile 2.54.0 (ANGLE ResourceMap static_assert, LayoutRect constexpr).
  • Backport the GStreamerCommon.h <WebCore/GraphicsTypesGL.h> include from upstream 2.54.1; GCC resolves the symlinked WebCore private headers to their real path, so the quoted include is not found when building the PCH.
  • Drop the vendored Skia backports for CVE-2026-5870, CVE-2026-7920, CVE-2026-7923, CVE-2026-10009 and CVE-2026-11663 (was Patch20..Patch24); the Skia snapshot bundled with 2.54.0 already includes them.
  • CVEs resolved by this rebase (62 total): CVE-2026-3538, CVE-2026-3909, CVE-2026-4460, CVE-2026-6298, CVE-2026-6364, CVE-2026-7353, CVE-2026-7949, CVE-2026-8510, CVE-2026-8579, CVE-2026-9983, CVE-2026-9998, CVE-2026-10011, CVE-2026-10977, CVE-2026-10985, CVE-2026-11024, CVE-2026-11039, CVE-2026-11057, CVE-2026-11099, CVE-2026-11121, CVE-2026-11124, CVE-2026-11159, CVE-2026-11675, CVE-2026-13971, CVE-2026-14389, CVE-2026-14414, CVE-2026-14427, CVE-2026-15766, CVE-2026-16417, CVE-2026-17702, CVE-2026-17745, CVE-2026-17757, CVE-2026-17914, CVE-2026-19160, CVE-2026-19161, CVE-2026-19176, CVE-2026-43804, CVE-2026-64713, CVE-2026-64728, CVE-2026-64730, CVE-2026-64753, CVE-2026-64757, CVE-2026-64778, CVE-2026-64779, CVE-2026-64782, CVE-2026-64783, CVE-2026-64784, CVE-2026-65332, CVE-2026-65336, CVE-2026-65337, CVE-2026-65341, CVE-2026-65351, CVE-2026-76041, CVE-2026-78376, CVE-2026-78914, CVE-2026-79020, CVE-2026-79112, CVE-2026-79144, CVE-2026-79147, CVE-2026-83596, CVE-2026-84359, CVE-2026-84635, CVE-2026-85049
