[Data] Add read_avro

[hebiao064]

Why are these changes needed?

Avro is a widely used data serialization system that integrates well with many big data processing environments. By supporting Avro data storage format for IO operations in Ray, we can enhance Ray's interoperability with the data ecosystem, making it easier for users to work with Avro files directly in their Ray applications. This addition aims to provide a seamless experience for users dealing with Avro formatted data for analytics, machine learning, and other data-intensive tasks.

Thanks!

Looks like the tests aren't currently run in CI. Could you update the BUILD file like how we've done for test_text?

ray/python/ray/data/BUILD

Lines 300 to 306 in d40ef0c

	py_test(
	name = "test_text",
	size = "small",
	srcs = ["tests/test_text.py"],
	tags = ["team:data", "exclusive"],
	deps = ["//:ray_lib", ":conftest"],
	)

Also, could you update input_output.rst?

ray/doc/source/data/api/input_output.rst

Lines 58 to 65 in d40ef0c
