[SPARK-14855][SQL] Add "Exec" suffix to physical operators

## What changes were proposed in this pull request?
This patch adds "Exec" suffix to all physical operators. Before this patch, Spark's physical operators and logical operators are named the same (e.g. Project could be logical.Project or execution.Project), which caused small issues in code review and bigger issues in code refactoring.

## How was this patch tested?
N/A
