Subject: [PATCH 06/41] ggml : do not define GGML_USE_CUDA when building with
 GGML_BACKEND_DL (#11211)

Build fails when using HIP and GGML_BACKEND_DL:
```
/usr/bin/ld: ../ggml/src/libggml.so: undefined reference to `ggml_backend_cuda_reg'
collect2: error: ld returned 1 exit status
```
This patch fixes this.

Subject: [PATCH 07/41] llama : remove 'd' from bad special token log (#11212)

This commit removes the 'd' from the log message in llama-vocab.cpp
when logging a bad special token.

The motivation for this is that currently the output can look something
like the following:
```console
load: bad special token:
    'tokenizer.ggml.image_token_id' = 128256d, using default id -1
```

+        LLAMA_VOCAB_TYPE_SPM  = 1,

+
+    - The `get` `` can be omitted
+    - The `` can be omitted if not necessary
+    - The `_context` suffix of the `` is optional. Use it to disambiguate symbols when needed
+    - Use `init`/`free` for constructor/destructor ``
+
+- Use the `_t` suffix when a type is supposed to be opaque to the user - it's not relevant to them if it is a struct or anything else
