What changes were proposed in this pull request?\r\n\r\nThis is the first step of the data source v2 API refactor [proposal](https://docs.google.com/document/d/1uUmKCpWLdh9vHxP7AWJ9EgbwB_U6T3EJYNjhISGmiQg/edit?usp=sharing)\r\n\r\nIt adds the new API for batch read, without removing the old APIs, as they are still needed for streaming sources.\r\n\r\nMore concretely, it adds\r\n1. `TableProvider`, works like an anonymous catalog\r\n2. `Table`, represents a structured data set.\r\n3. `ScanBuilder` and `Scan`, a logical represents of data source scan\r\n4. `Batch`, a physical representation of data source batch scan.\r\n\r\n## How was this patch tested?\r\n\r\nexisting
