chore: Fix whitespace (#6243)

* fix: Remove spurious blank lines

  Remove extraneous blank lines introduced by deletion of
  'use strict'; pragmas.

  Also fix the location of the goog.declareModuleId call in
  core/utils/array.ts.

* fix: Add missing double-blank-line before body of modules

  Our convention is to have two blank lines between the imports (or
  module ID, if there are no imports) and the beginning of the body
  of the module.  Enforce this.

* fix: one addition format error for PR #6243
