### What changes were proposed in this pull request?
separate the configuration keys "spark.sql.optimizer.maxIterations" and "spark.sql.analyzer.maxIterations".

### Why are the changes needed?
Currently, both Analyzer and Optimizer use conf "spark.sql.optimizer.maxIterations" to set the max iterations to run, which is a little confusing.
It is clearer to add a new conf "spark.sql.analyzer.maxIterations" for analyzer max iterations.

### Does this PR introduce any user-facing change?
no

### How was this patch tested?
Existing unit tests.

Closes #26766 from fuwhu/SPARK-30138.
