Specify library name and version: diligent-tools/all

This is also a good place to share with all of us why you are submitting this PR (specially if it is a new addition to ConanCenter): is it a dependency of other libraries you want to package? Are you the author of the library? Thanks!

@jgsogo @prince-chrismc I have a challange here.

diligent-tools tries to install some python package via pip:
https://github.com/DiligentGraphics/DiligentTools/blob/e604522a83d2186f9df823515751c8034b7fb7e8/RenderStateNotation/CMakeLists.txt#L26

As I understand, it it forbidden in conan CI. At least, previous builds failed because of it.
As I see, they are required in some other python build scripts.

Is it possible to get/import these packages via conanfile?

@AndreyMlashkin No way. If libclang need to be installed as mandatory dependency, I would say to take a look on llvm-core package, otherwise, it will need a new package.

Pip will install other packages, but Conan will not be able to manage it, it will affect the package id, but we have no hint about it, it will always the same, but pip can change anything and we will not track.

In the very very past, I did a workaround involving Conan + pip, using pip.main(). But still, is not something to be used here. Sorry.

I will remove adding of a new version for now
