The Path class is currently mutable to support the IOReadableWritable serialization. However, but many parts of the code assume that the Path is immutable. The mutable Path class is prone to subtle errors. By making the URI in the Path class immutable, the path can be properly stored without the risk of being mutated. we can ensure that paths are stored correctly without the possibility of mutation and eliminate the occurrence of subtle errors.
Public Interfaces
Modify the Path class to no longer implement the IOReadableWritable interface.

First, add the two static methods to the Path class to support serialization and deserialization. Currently, three classes need to serialize/deserialize the Path using the IOReadableWritable interface: FileSourceSplitSerializer/TestManagedSinkCommittableSerializer/TestManagedFileSourceSplitSerializer. Modify these classes to serialize/deserialize the Path using the two static methods instead of IOReadableWritable.
