Previously, the journal writer is nil until the first time rejournal
(default 1h), which means during this period, txs submitted to this node
are not written into journal file (transactions.rlp). If this node is
shutdown before the first time rejournal, then txs in pending or queue
will get lost.
Here, this PR initializes the journal writer soon after launch to solve
this issue.

In this pull request, the original `CacheConfig` has been renamed to `BlockChainConfig`.
Over time, more fields have been added to `CacheConfig` to support
blockchain configuration. Such as `ChainHistoryMode`, which clearly extends
beyond just caching concerns.
Additionally, adding new parameters to the blockchain constructor has
become increasingly complicated, since it’s initialized across multiple
places in the codebase. A natural solution is to consolidate these arguments
into a dedicated configuration struct.
As a result, the existing `CacheConfig` has been redefined as `BlockChainConfig`.
Some parameters, such as `VmConfig`, `TxLookupLimit`, and `ChainOverrides`
have been moved into `BlockChainConfig`. Besides, a few fields in `BlockChainConfig`
were renamed, specifically:
- `TrieCleanNoPrefetch` -> `NoPrefetch`
- `TrieDirtyDisabled` -> `ArchiveMode`
Notably, this change won't affect the command line flags or the toml
configuration file. It's just an internal refactoring and fully backward-compatible.

This pull request improves error handling for local transaction submissions.
Specifically, if a transaction fails with a temporary error but might be
accepted later, the error will not be returned to the user; instead, the
transaction will be tracked locally for resubmission.
However, if the transaction fails with a permanent error (e.g., invalid
transaction or insufficient balance), the error will be propagated to the user.
These errors returned in the legacyPool are regarded as temporary failure:
- `ErrOutOfOrderTxFromDelegated`
- `txpool.ErrInflightTxLimitReached`
- `ErrAuthorityReserved`
- `txpool.ErrUnderpriced`
- `ErrTxPoolOverflow`
- `ErrFutureReplacePending`
Notably, InsufficientBalance is also treated as a permanent error, as
it’s highly unlikely that users will transfer funds into the sender account
after submitting the transaction. Otherwise, users may be confused—seeing
their transaction submitted but unaware that the sender lacks sufficient funds—and
continue waiting for it to be included.

In transaction-sending APIs such as `eth_sendRawTransaction`, a submitted transaction
failing the configured txpool validation rules (i.e. fee too low) would cause an error to be
returned, even though the transaction was successfully added into the locals tracker.
Once added there, the transaction may even be included into the chain at a later time,
when fee market conditions change.
This change improves on this by performing the validation in the locals tracker, basically
skipping some of the validation rules for local transactions. We still try to add the tx to the
main pool immediately, but an error will only be returned for transactions which are
fundamentally invalid.

This is a not-particularly-important "cleanliness" PR. It removes the
last remnants of the `x/exp` package, where we used the `maps.Keys`
function.
The original returned the keys in a slice, but when it became 'native'
the signature changed to return an iterator, so the new idiom is
`slices.Collect(maps.Keys(theMap))`, unless of course the raw iterator
can be used instead.
In some cases, where we previously collect into slice and then sort, we
can now instead do `slices.SortXX` on the iterator instead, making the
code a bit more concise.
This PR might be _slighly_ less optimal, because the original `x/exp`
implementation allocated the slice at the correct size off the bat,
which I suppose the new code won't.
Putting it up for discussion.

Replaces #29297, descendant from #27535
---------
This PR removes `locals` as a concept from transaction pools. Therefore,
the pool now acts as very a good simulation/approximation of how our
peers' pools behave. What this PR does instead, is implement a
locals-tracker, which basically is a little thing which, from time to
time, asks the pool "did you forget this transaction?". If it did, the
tracker resubmits it.
If the txpool _had_ forgotten it, chances are that the peers had also
forgotten it. It will be propagated again.
Doing this change means that we can simplify the pool internals, quite a
lot.
### The semantics of `local`
Historically, there has been two features, or usecases, that has been
combined into the concept of `locals`.
1. "I want my local node to remember this transaction indefinitely, and
resubmit to the network occasionally"
2. "I want this (valid) transaction included to be top-prio for my
miner"
This PR splits these features up, let's call it `1: local` and `2:
prio`. The `prio` is not actually individual transaction, but rather a
set of `address`es to prioritize.
The attribute `local` means it will be tracked, and `prio` means it will
be prioritized by miner.
For `local`: anything transaction received via the RPC is marked as
`local`, and tracked by the tracker.
For `prio`: any transactions from this sender is included first, when
building a block. The existing commandline-flag `--txpool.locals` sets
the set of `prio` addresses.
