Implements function to return custom message if one exists.

`CustomMessage_RetrieveIfExists` is placed at the very beginning of the z_message_PAL.c `Message_OpenText` if statement after any special changes to textIds are made. This function will either return either true or false and if true it will populate the necessary values of font and msgCtx to display said message. It's placement at the beginning also allows for overriding existing textIds to have new information, which will come in handy later.
