Coding Standards: Use strict comparison where static strings are involved.
This reduces the number of `WordPress.PHP.StrictComparisons.LooseComparison` issues in half, from 1897 to 890. Includes minor code layout fixes for better readability. See #49542. git-svn-id: https://develop.svn.wordpress.org/trunk@47808 602fd350-edb4-49c9-b593-d223f7449a82
