Support static xcframework packaging in build-xcframework.sh (#3322)

Browse Source 
* This commit allows for the building of a static xcframework by adding a
BUILD_STATIC_XCFRAMEWORK option. When enabled, the build-xcframework.sh
script builds a self-contained static whisper.xcframework.

The motivation for this change is so that command line binaries can link
whisper.cpp without forcing users to install the whisper.xcframework
separately.

* Update build-xcframework.sh
