Add C++ gguf reader into cmake, add python gguf reader example

[cmp-nct]

The existing gguf example is not present in the cmake examples, now it can be compiled.
It appears to work, though the data print won't work.

In addition I added a reader.py which prints information about a gguf file.
I'm sure it is far from perfect or complete, but provides a base to start with.

Example output:

python reader.py  ggml-model-q4k.gguf

I'm not sure how the procedure for merges is on github

Maybe that's why the gguf example lay dormant, or it was too long dormant.
Can we just not include it into vulkan by a cmake flag ?

Adding the gguf into cmake is a super minor thing, I'm sorry if that broke something unexpected.
If the solution isn't straight forward we should either revert the cmake addition or exclude it for incompatible platforms/libraries

Not sure, this might be an issue on the Vulkan side, since it doesn't seem to happen with other backends. The Vulkan CMake code is a little different from the other backends, and that's the cause of this issue.

@netrunnereve If I revert #5230 , this issue is resolved for me. But that was problematic on Windows. Any ideas?

[ggerganov]

Maybe we can change the Vulkan objects to be part of ggml lib similar to other backends.

Instead of having separate ggml-vulkan target:

I think we may have to do what @ggerganov suggested and move everything to the ggml lib rather than creating a seperate ggml-vulkan object (you can test his patch at #5525). As @sorasoras mentioned the ROCM build is also failing, and ROCM is built using a seperate object just like Vulkan.
