 Propose adding seeking capability to the `WP_Test_Stream` in-memory
 streamWrapper.

 Seeking is required for automated testing of Media streams for functions
 such as

 - `getimagesize` (used in `wp_getimagesize`)
 - `exif_read_data` (used in `wp_read_image_metadata`)

 For example, #52826 notes an issue with streams; however, integration
 tests are blocked due to `WP_Test_Stream` not supporting seeking.
