refactor: use extensible request handlers

[Wodann]

This is a draft PR exploring a design for request handlers that's extensible for different chain types and (potentially) third party extensions.

The new design allows us to generate documentation per handler, instead of having to extract documentation from the large enum MethodInvocation type.

To do

• Split research into two PRS:
  1. Refactor error propagation
  2. Dynamic request handlers
• Investigate performance impact of switching from match statement to dynamic trait objects
