[FLINK-8012] [table] Fix TableSink config for tables with time attributes.
## What is the purpose of the change
Fix the configuration of TableSinks for Tables with time attributes
(`TimeIndicatorTypeInfo`).
Time indicators types are internal and must not be exposed to the outside
(such as TableSinks).
## Brief change log
* the field type of time attributes (rowtime or proctime) is changed to
their publicly visible type `SQL_TIMESTAMP`.
* an existing test is adapted to check this case.
## Verifying this change
* an existing test method in `TableSinkITCase` was adapted.
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): **no**

`@Public(Evolving)`: **no**
- The serializers: **no**
- The runtime per-record code paths (performance sensitive): **no**
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: **no**
- The S3 file system connector: **no**
## Documentation
- Does this pull request introduce a new feature? **no**
- If yes, how is the feature documented? **n/a**
