Harfbuzz libraries update (#2191)

* Update harfbuzz-icu-freetype with latest library versions

* Add more location presets for checking text in GlfwApp

* Revise and document Apple fallback font list

* Store iOS CMake log on CI

* Store iOS CMake errors on CI

* Update harfbuzz-icu-freetype submodule with build fixes

* Revert "Store iOS CMake errors on CI" and "Store iOS CMake log on CI"

More practical to debug these issues by accessing the build container with SSH

* Remove references to UCDN

No longer needed separately from harfbuzz
