GS/HW: Fix dirty check on SWPrimRenderer check

The game list comparator previously used >= when sorting by CRC in
descending order. This violates the requirements of a strict weak
ordering, as defined by the C++ standard, which mandates that the
comparator must be irreflexive: comp(x, x) must always return false.

Using >= causes comp(a, b) and comp(b, a) to both return true when
a == b, which breaks the irreflexivity and can invalidate the
assumptions made by std::sort. This may lead to undefined behavior,
including memory corruption or segmentation faults.

Replace >= with > to ensure the comparator satisfies the strict weak
ordering requirement, restoring correctness and stability in game list
sorting behavior.

-
-## Pull Request Guidelines
-
-The following is a list of *general* style recommendations that will make reviewing and merging easier:
-
-*   Commit Messages
-    *   Please try to prefix your commit message, indicating what area of the project was modified.
-        *   For example `gs: message...`.
-        *   Looking at the project's commit history will help with keeping prefixes consistent overtime, *there is no strictly enforced list*.
-
-    *   Try to keep messages brief and informative
-
-    *   Remove unnecessary commits and squash commits together when appropriate.
-        *   If you are not familiar with rebasing with git, check out the following resources:
-            *   CLI - https://thoughtbot.com/blog/git-interactive-rebase-squash-amend-rewriting-history
-            *   GUI (SourceTree) - https://www.atlassian.com/blog/sourcetree/interactive-rebase-sourcetree
-
-*   Code Styling and Formatting
-    *   [Consult the style guide](https://github.com/tadanokojin/pcsx2/blob/coding-guide/pcsx2/Docs/Coding_Guidelines.md)
-
-    *   Run `clang-format` using the configuration file in the root of the repository
-        *   Visual Studio Setup - https://devblogs.microsoft.com/cppblog/clangformat-support-in-visual-studio-2017-15-7-preview-1/
-        *   IMPORTANT - if you are running `clang-format` on unrelated changes (ie. formatting an entire file), please do so in a separate commit.
-            *   If you cannot scope your `clang-format` to just your changes and do not want to format unrelated code.  Try your best to stick with the existing formatting already established in the file in question.
