macOS: Support IME

Browse Source 
This commit re-organizes 31b12b7f79a5aa8bd8f8eb1488a050ab894ca289.

* Use dynamic load for TIS functions and stop using Carbon.
* Generalize platform-specific features to _GLFWplatform.
* Add caret-position info to preedit-callback.
* Handle UTF16 data correctly.
* Implement `firstRectForCharacterRange:actualRange:` to display preedit candidate window correctly.
* Suppress _glfwInputKey during preediting.
* Ensure preedit cleared after committed.
* Fix wrong length of markedRange.
* Improve IME status APIs.
* Refactor code shapes and variable names.
