[macOS] Command-backspace in line edit

Make command-backspace in line edit work like other macOS applications. If there is a selection, command-backspace deletes the selection. If there isn't a selection, command-backspace deletes from the cursor to the beginning of the line edit. This addresses part of godotengine/godot#23548
