feat: enable account changesets on save_blocks

[joshieDo]

• Adds account changesets to the segment list being written in parallel on SF
• Adds the struct below so we can cover cases when we call write_state BUT we have already written either receipts or account changesets elsewhere.
  • reth-edge will always pass false through save_blocks (they get written to SF in parallel) but MIGHT call it with true in other usages (eg. tests, legacy nodes writing fully to mdbx)

/// Configuration for what to write when calling [`StateWriter::write_state`].
///
/// Used to skip writing certain data types, when they are being written separately.
#[derive(Debug, Clone, Copy)]
pub struct StateWriteConfig {
    /// Whether to write receipts.
    pub write_receipts: bool,
    /// Whether to write account changesets.
    pub write_account_changesets: bool,
}
