(core) Summary columns improvemnt.

Summary:
Improving user experience on summary columns.
- Showing 'not-allowed' cursor on sections/menus that can't be changed
- Disabling menu options and buttons in the column behavior section that converts a formula column to a data column
- Showing nicer error message about converting formula to a data column.

Test Plan: manual tests, no behavior change
