[Open for discussion] Refine dependencies

[zxzxwu]

(I haven't updated documentation because I think there will be some discussions)

Our dependency groups is a bit complicated right now. There have been some small problems like:

1. The number of optional dependency group is increasing
2. Divergent cryptography version requirement
3. Highly specialized dependencies for Emscripten
4. Apps dependencies are marked mandatory
5. Not everyone needs all transports

So here we apply some changes:

• Move dev-only deps to [dependency-groups]
• Add a all option including all other options
• Add app and transport options
  • This might be debatable?
• Replace appdirs with platformdirs

Also some questions:

• On https://pyodide.org/en/stable/usage/packages-in-pyodide.html it shows that platformdirs is supported, so maybe we can remove platform_system!='Emscripten' condition? I am not pretty sure how does dependency for pyodide work.

Maybe avatar and pandora should be removed from all option since most users don't need them. I am planning to remove them from Bumble (including bumble.pandora) later this year since we have almost stopped maintaining them publicly.
