Most frame types have identical or very similar implementation for GetMinISize() and GetPrefISize(), and many of them already have `IntrinsicISize()` to unify the implementation. This patch introduces nsIFrame::IntrinsicISize() so that derived classes only need to override one method. `nsBlockFrame`, `ColumnSetWrapperFrame`, and `nsColumnSetFrame` are the only three classes where their `GetMinISize()` and `GetPrefISize()` have significant differences. Therefore, we rename `GetMinISize()` and `GetPrefISize()` to `MinISize()` and `PrefISize`, respectively, and use them as helpers to implement their `IntrinsicISize()`. This patch doesn't change behavior. Differential Revision: https://phabricator.services.mozilla.com/D217790
