[SPARK-14138] [SQL] [MASTER] Fix generated SpecificColumnarIterator code can exceed JVM size limit for cached DataFrames
## What changes were proposed in this pull request?
This PR reduces Java byte code size of method in ```SpecificColumnarIterator``` by using a approach to make a group for lot of ```ColumnAccessor``` instantiations or method calls (more than 200) into a method
## How was this patch tested?
Added a new unit test, which includes large instantiations and method calls, to ```InMemoryColumnarQuerySuite```
