This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21.
Main changes are as follows:
* removes any log handlers that were unused in the Geth codebase.
* Json, logfmt, and terminal formatters are now slog handlers.
* Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options.
* `--log.backtraceat` and `--log.debug` are removed.
The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged.
A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed.

For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did
```golang
log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true))))
```
You now instead need to do
```golang
log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true)))
```

* cmd, les, tests: remove light client code
This commit removes the light client (LES) code.
Since the merge the light client has been broken and
it is hard to maintain it alongside the normal client.
We decided it would be best to remove it for now and
maybe rework and reintroduce it in the future.
* cmd, eth: remove some more mentions of light mode
* cmd: re-add flags and mark as deprecated
* cmd: warn the user about deprecated flags
* eth: better error message
geth --dev can be used with an existing data directory and genesis block. Since
dev mode only works with PoS, we need to verify that the merge has happened.

This change allows the creation of a genesis block for verkle testnets. This makes for a chunk of code that is easier to review and still touches many discussion points.
* cmd, core: resolve scheme from a read-write database
* cmd, core, eth: move the scheme check in the ethereum constructor
* cmd/geth: dump should in ro mode
* cmd: reverts
This fixes an issue where the --bootnodes flag was overridden by the config file.

Add a new flag, `--pluginsdir`, for setting the directory where plugins are stored. The default remains `$datadir/plugins`.

This change removes PoW header syncing related code from LES and also deletes
duplicated packages les/catalyst, les/downloader and les/fetcher. These package copies
were created because people wanted to make changes in their eth/ counterparts, but weren't
able to adapt LES code to the API changes.
This simplifies the code that initializes the discovery a bit, and
adds new flags for enabling/disabling discv4 and discv5 separately.

The clean trie cache is persisted periodically, therefore Geth can
quickly warmup the cache in next restart.
However it will reduce the robustness of system. The assumption is
held in Geth that if the parent trie node is present, then the entire
sub-trie associated with the parent are all prensent.
Imagine the scenario that Geth rewinds itself to a past block and
restart, but Geth finds the root node of "future state" in clean
cache then regard this state is present in disk, while is not in fact.
Another example is offline pruning tool. Whenever an offline pruning
is performed, the clean cache file has to be removed to aviod hitting
the root node of "deleted states" in clean cache.
All in all, compare with the minor performance gain, system robustness
is something we care more.
* all: move main transaction pool into a subpool
* go.mod: remove superfluous updates
* core/txpool: review fixes, handle txs rejected by all subpools
* core/txpool: typos
