[SPARK-14577][SQL] Add spark.sql.codegen.maxCaseBranches config option
## What changes were proposed in this pull request?
We currently disable codegen for `CaseWhen` if the number of branches is
greater than 20 (in CaseWhen.MAX_NUM_CASES_FOR_CODEGEN). It would be better if
this value is a non-public config defined in SQLConf.
## How was this patch tested?
Pass the Jenkins tests (including a new testcase `Support
spark.sql.codegen.maxCaseBranches option`)
