Here, the core.Message interface turns into a plain struct and
types.Message gets removed.

This is a breaking change to packages core and core/types. While we do
not promise API stability for package core, we do for core/types. An
exception can be made for types.Message, since it doesn't have any
purpose apart from invoking the state transition in package core.
types.Message was also marked deprecated by the same commit it
got added in, 4dca5d4d (November 2016).

The core.Message interface was added in December 2014, in commit
db494170, for the purpose of 'testing' state transitions. It's the
same change that made transaction struct fields private. Before that,
the state transition used *types.Transaction directly.

Over time, multiple implementations of the interface accrued across
different packages, since constructing a Message is required whenever
one wants to invoke the state transition. These implementations all
looked very similar, a struct with private fields exposing the fields
as accessor methods.

By changing Message into a struct with public fields we can remove all
these useless interface implementations. It will also hopefully
simplify future changes to the type with less updates to apply across
all of go-ethereum when a field is added to Message.

Currently, setDefaults overwrites the transaction input value if only input is provided. This causes personal_sendTransaction to estimate the gas based on a transaction with empty data. eth_estimateGas never calls setDefaults so it was unaffected by this.

Ticket #23273 found a flaw where we were unable to sign legacy-transactions
using the external signer, even if we're still on non-london network. That's
fixed in this PR.

Additionally, I found that even when supplying all parameters, it was impossible
to sign a london-transaction on an unsynched node. It's a pretty common usecase
that someone wants to sign a transaction using an unsynced 'vanilla' node,
providing all necessary data. Our setDefaults, however, insisted on checking the
current block against the config. This PR therefore adds a case, so that if both
MaxPriorityFeePerGas and MaxFeePerGas are provided, we accept them as given.

OBS This PR fixes a regression -- on current master, we are unable to sign a
london-transaction unless the node is synched, which may break scenarios where
geth (or clef) is used as a cold wallet.

There are two transaction parameter structures defined in
the codebase, although for different purposes. But most of
the parameters are shared. So it's nice to reduce the code
duplication by merging them together.
