[SPARK-24157][SS][FOLLOWUP] Rename to spark.sql.streaming.noDataMicro…

…Batches.enabled

## What changes were proposed in this pull request?
This patch changes the config option `spark.sql.streaming.noDataMicroBatchesEnabled` to `spark.sql.streaming.noDataMicroBatches.enabled` to be more consistent with rest of the configs. Unfortunately there is one streaming config called `spark.sql.streaming.metricsEnabled`. For that one we should just use a fallback config and change it in a separate patch.

## How was this patch tested?
Made sure no other references to this config are in the code base:
```
> git grep "noDataMicro"
sql/catalyst/src/main/scala/org/apache/spark/sql/internal/SQLConf.scala:    buildConf("spark.sql.streaming.noDataMicroBatches.enabled")
```

Closes #22476 from rxin/SPARK-24157.
