Remove inheritance of built-in column types, improve readability of column type classes, fix getters that returns columns from data tables

[Kreyu]

Breaking changes

• Moved columns priority and visibility properties and their getters and setters from column to their config. This should not affect most of the applications, unless those methods were accessed manually.
• Removed previously deprecated setName, setOptions and setOption methods in column builder.
• Removed previously deprecated FormColumnType.
• Removed column type inheritance in built-in column types, which includes:
  • DateColumnType no longer uses DateTimeColumnType as its parent
  • DatePeriodColumnType no longer uses DateTimeColumnType as its parent
  • DateTimeColumnType no longer uses TextColumnType as its parent
  • EnumColumnType no longer uses TextColumnType as its parent
  • LinkColumnType no longer uses TextColumnType as its parent
  • LinkColumnType no longer uses TextColumnType as its parent
  • MoneyColumnType no longer uses NumberColumnType as its parent
  • NumberColumnType no longer uses TextColumnType as its parent

Therefore, every built-in column type is using base ColumnType as its parent. This fixes an issue where creating type extension for one type (e.g. TextColumnType) was incorrectly affecting other built-in types, without a way to prevent that.

Now, for example, if you want to create a column type extension for both TextColumnType and NumberColumnType, provide both of those types from the extension's getExtendedTypes() method.

Changes

• Updated definition of all built-in column types with a short description and a link to its reference page in the documentation.
• Updated definition of all built-in column types options to use fluent interface with short description, which improved readability.
• Fixed getColumns, getVisibleColumns, getHiddenColumns and getExportableColumns methods from DataTable class returning columns in incorrect order and visibility when using personalization
