[SPARK-20555][SQL] Fix mapping of Oracle DECIMAL types to Spark types
## What changes were proposed in this pull request?
This change removes the custom code from `OracleDialect`, that was mapping
some of Oracle's `DECIMAL(X, Y)` types to `BooleanType`, `IntegerType`,
`LongType` or `FloatType`.
## How was this patch tested?
I used the following command to run the docker-bases integration tests:
```
./build/mvn -Pdocker-integration-tests -pl
:spark-docker-integration-tests_2.11 test
```
