Adds asAlias property to INSERT AST node

[johnedquinn]

Relevant Issues

• Closes INSERT with alias loses original table name which is replaced with the alias #1043

Description

• Breaking: Adds asAlias nullable property to the insert AST node.
• Modifies tests corresponding to the change
• This PR does NOT add the alias to the DML Conflict Action -- as the current planner does NOT support any action besides EXCLUDED -- which does not reference the alias. This will need to be addressed once we extend support to the conflict action value to include SET/VALUE according to the RFC.

Other Information

• Updated Unreleased Section in CHANGELOG: YES
• Any backward-incompatible changes? YES
  • Yes, the public AST node insert now contains another property called asAlias
• Any new external dependencies? NO
