Add dedicated functions for reading the blockbody

[mattsse]

Describe the feature

we currently only have:

reth/crates/storage/storage-api/src/block.rs

Lines 76 to 79 in bec4510

	/// Returns the block with given id from the database.
	///
	/// Returns `None` if block is not found.
	fn block(&self, id: BlockHashOrNumber) -> ProviderResult<Option<Self::Block>>;

and

reth/crates/storage/provider/src/providers/database/provider.rs

Lines 1181 to 1209 in bec4510

	/// Returns the block with matching number from database.
	///
	/// If the header for this block is not found, this returns `None`.
	/// If the header is found, but the transactions either do not exist, or are not indexed, this
	/// will return None.
	fn block(&self, id: BlockHashOrNumber) -> ProviderResult<Option<Self::Block>> {
	if let Some(number) = self.convert_hash_or_number(id)? {
	if let Some(header) = self.header_by_number(number)? {
	// If the body indices are not found, this means that the transactions either do not
	// exist in the database yet, or they do exit but are not indexed.
	// If they exist but are not indexed, we don't have enough
	// information to return the block anyways, so we return `None`.
	let Some(transactions) = self.transactions_by_block(number.into())? else {
	return Ok(None)
	};
	let body = self
	.storage
	.reader()
	.read_block_bodies(self, vec![(&header, transactions)])?
	.pop()
	.ok_or(ProviderError::InvalidStorageOutput)?;
	return Ok(Some(Self::Block::new(header, body)))
	}
	}
	Ok(None)
	}

we can add another function dedicated to the blockbody

TODO

• add trait fn for block_body and impl it accordingly
