eth/tracers, core: use scopecontext in tracers, provide statedb in capturestart (#22333)

Browse Source 
Fixes the CaptureStart api to include the EVM, thus being able to set the statedb early on. This pr also exposes the struct we used internally in the interpreter to encapsulate the contract, mem, stack, rstack, so we pass it as a single struct to the tracer, and removes the error returns on the capture methods.
