Use `bytes::Bytes` as underlying representation for bytes value

[badmonster0]

Currently we're using Arc[u8] for bytes.

• As KeyValue:

  cocoindex/src/base/value.rs

  Line 76 in 79072fb

  Bytes(Arc<[u8]>),

• As Value:

  cocoindex/src/base/value.rs

  Line 345 in 79072fb

  Bytes(Arc<[u8]>),

Crate bytes provides a more flexible and efficient way to represent bytes (e.g. if we want a slice of it, we don't need to make a copy). It's widely used by other libraries. We need to do a conversion to interchange with them, e.g. conversion for neo4rs:

cocoindex/src/ops/storages/neo4j.rs

Line 285 in 762031a

BoltType::Bytes(neo4rs::BoltBytes::new(bytes::Bytes::from_owner(v.clone())))

We want to switch to use bytes::Bytes for cocoindex's values.
