Context

The x/bsonx/bsoncore and x/mongo/driver/wiremessage packages both contain duplicate implementations of low-level binary operations that should be centralized.

Definition of done

Add the following functions to binaryutil internal package and remove their analogues in wiremessage and bsoncore packages:

1. AppendU32(dst []byte, u32 uint32) []byte
2. AppendU64(dst []byte, u64 uint64) []byte
3. ReadU32(src []byte) (uint32, []byte, bool)
4. ReadU64(src []byte) (uint64, []byte, bool)
5. ReadCString(src []byte) (string, []byte, bool)
