feat(storage): write headers and transactions only to static files

[shekhirin]

Closes #18683
Closes #11524

Removes the StorageLocation enum that was used to tell the provider where to write the data. Headers and transactions now are always written to static files only.

This doesn't break existing nodes, because on startup we always copy to static files

reth/crates/node/builder/src/launch/engine.rs

Lines 159 to 160 in aa192c2

	// The new engine writes directly to static files. This ensures that they're up to the tip.
	pipeline.move_to_static_files()?;

---

We need to figure out what to do with receipts pruning. We support receipts_log_filter option that can prune everything but certain receipts that match the log filter, and use it for NOT pruning the deposit contract receipts. This type of pruning can't be done with static files, as they don't support deletions in the middle of the file.

For now, I'm still always writing receipts to the database, and to static files only if pruning is not enabled.

It's a lot of changes but 80% looks like removing the StorageLocation argument from everything so pretty straightforward. LGTM

unsure here, if this is called after/during an unwind this would technically be wrong right? UnifiedStorageWriter::commit_unwind exists

[mattsse]

makes sense,

lgtm!
