Upload: Correct duplicate MIME type for .xlsx files generated by Google Docs.

Browse Source 
This expands the code block previously added for `.docx` files to include `.xlsx` files as well, which are known to have the same issue with `finfo_file()`.

Includes a unit test case for `wp_check_filetype_and_ext()`.

Reference: [https://bugs.php.net/bug.php?id=77784 PHP Bug #77784: mime_content_type() result gets doubled for .xlsx].

Follow-up to [56497].

See #57898.
