[FLINK-7420] [avro] Move all Avro code to flink-avro (followup)
## What is the purpose of the change
This is an extension of #4931 which adds some cleanups and improvements.
Most notably, it makes the new `flink-avro` module independent of runtime
dependencies and Scala versions.
## Brief change log
- Move the `SerializationSchema` classes to `flink-core` to make them
accessible from API projects without introducing runtime dependencies. This is
done in a non-API-breaking way.
- Make `flink-avro` module independent of `flink-streaming-java`,
`flink-runtime` and hence independent of Scala versions.
- Add various cleanups and fixes
- Adds a test that validates that a KryoSerializer from Flink 1.3 (which
has implicit Avro dependency classes) is still deserializable with the state
serializer utils (that implement the serializer and state evolution).
## Verifying this change
- Most of the changes are covered by existing tests
- Adds a test that validates that a KryoSerializer from Flink 1.3 (which
has implicit Avro dependency classes) is still deserializable with the state
serializer utils (that implement the serializer and state evolution).
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): (**yes** / no):
**This changes the `flink-avro` module to be Scala independent.
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: (**yes** / no): **Moves the SerializationSchema classes,
but leaves old classes in place (extending new classes) to preserve the API
compatibility**.
- The serializers: (yes / **no** / don't know)
- The runtime per-record code paths (performance sensitive): (yes /
**no** / don't know)
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know)
-
## Documentation
- Does this pull request introduce a new feature? (yes / **no**)
- If yes, how is the feature documented? (**not applicable** / docs /
JavaDocs / not documented)

[FLINK-7972] [core] Move SerializationSchema to 'flink-core'
Moves the SerializationSchema and its related from
flink-streaming-java to flink-core.
That helps API level projects that depend on those classes
to not pull in a dependency on runtime classes, and to
not be Scala version dependent.

[FLINK-7420] [avro] Replace GenericData.Array by dummy when reading
TypeSerializers
This also adds a new test that verifies that we correctly register
Avro Serializers when they are present and modifies an existing test to
verify that we correctly register dummy classes.

[FLINK-7420] [avro] Abstract all Avro interaction behind AvroUtils
Before, we would try and dynamicall load Avro-related classes in several
places. Now, we only reflectively instantiate the right AvroUtils and
all other operations are methods on this.
The default AvroUtils throw exceptions with a helpful message for most
operations.

[FLINK-7420] [avro] Make flink-avro Scala independent
This removes all dependencies on Scala-dependent projects.
This commit introduces a hard wired test dependency to
'flink-test-utils_2.11' to avoid introducing a Scala version dependency
due to a non-exported test utility.

[hotfix] [avro] Simplify the FSDataInputStreamWrapper
The FSDataInputStreamWrapper comes from a time when Flink's
FsDataInputStream was not
position aware. Not that it is, the FSDataInputStreamWrapper is not
required to track
its own position, but can simply delegate these calls to the
FsDataInputStream.
This also adds missing @Override tags.

This also fixes minor warnings (unchecked casts) and moves the constants
