ruby : add Core ML support (#3214)

Browse Source 
* Prevent overflow

* Fix memsize of Whisper::Context

* Rename xxx_initialize to more Ruby-esque name: xxx_s_new

* Define Whisper::Model::ZipURI

* Define Whisper::Model.coreml_compiled_models

* Make Options' @cmake_options Hash

* Use --{enable,disable}-whisper-coreml option for -I/opt/homebrew/opt/llvm/include

* Prepare Core ML model if enabled

* Add test for ZipURI

* Add signatures for ZipURI

* Add Whisper.system_info_str

* Add test for Whisper.system_info_str

* Add signagure for Model.coreml_compiled_models

* Add signature for Whisper.system_info_str

* Add test for Core ML

* Update date

* Maintain .gitignore
