[Suggestion] Reduce API surface of ggml.h

[howard0su]

The latest ggml.h expose all the details of ggml_tensor and the related OP names. This may causes compatibility problems later as the consumer may direct access the fields of tensor. In the world of binary compatibility, this introduce maintenance headache.

Proposed Changes:

1. hide ggml_tensor details, add couple of helper functions like ggm_tensor_size, _nb, _ne etc to expose necessary information.
2. Create ggml-internal.h and move internal interface to that including tensor struct, op definitions etc.

If we agree, I can propose a change.

@ggerganov love to hear you option before we move forward.

Such change can happen at a much later stage of the development.
Right now, it's more important to access the structs in a comfortable and convenient way - no need to worry about binary compatibility.

Later, let's say for V1, such change could be made.
But now it will just make our lives harder having to write getters and setters all the time.
