Context

txpool is basically Geth mempool. This MR implements the encoding and the RPC. I suggest to have a look at https://geth.ethereum.org/docs/interacting-with-geth/rpc/ns-txpool to understand the encoding itself (it is also documented).

This txpool RPC will be used in the future for the delayed inbox.

Manually testing the MR

The content of the txpool is not relevant for now, but I've added a test that checks the format of the RPC:

dune exec tezt/tests/main.exe -- --file evm_rollup.ml --match "txpool"

Document the interface of any function added or modified (see the coding guidelines)
