ggml update to 0.11.0， llama-cpp update to 9030

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version, or no changes were necessary.
• Any fixed CI baseline and CI feature baseline entries are removed from that file, or no entries needed to be changed.
• All patch files in the port are applied and succeed.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Exactly one version is added in each modified versions file.

• Switch vendored libs to system vcpkg ports:
  • cpp-httplib → vcpkg port (header-only, always needed by common lib)
  • nlohmann-json → vcpkg port (header-only, always needed by common lib)
  • stb → vcpkg port (header-only, needed by mtmd/tools)
  • miniaudio → vcpkg port (header-only, needed by mtmd/tools)
• Keep vendored: sheredom/subprocess.h (no vcpkg port available)
• Patch include paths (stb, miniaudio, cpp-httplib) and CMake target names (cpp-httplib → httplib::httplib)
• Add new patch: unvendor.diff

     add_subdirectory(common)
-    add_subdirectory(vendor/cpp-httplib)
+    find_package(httplib CONFIG REQUIRED)
+    add_library(cpp-httplib ALIAS httplib::httplib)

would avoid of changing all the uses of cpp-httplib (and still export httplib::httplib to cmake config).

... And we probably need a find_dependency(httplib CONFIG) in the cmake confiug file (unless it is only used in executables - check the export).

[miyanyan]

cpp-httplib is only linked privately by llama-common:

target_link_libraries(llama-common PRIVATE cpp-httplib)

and llama-common is not exported as a CMake target in the installed package. The generated llama-config.cmake only creates/imports the llama target, whose interface links to ggml. So httplib is not part of the public CMake interface for consumers.

Merged with master to pick up CUDA version change from #51210.
