Joe McGill ce1a73f7d4 Media: Improve image filetype checking. ...

This adds a new function `wp_get_image_mime()` which is used by
`wp_check_filetype_and_ext()` to validate image files using
`exif_imagetype()` if available instead of `getimagesize()`.

`getimagesize()` is less performant than `exif_imagetype()` and is
dependent on GD. If `exif_imagetype()` is not available, it falls back to
`getimagesize()` as before.

If `wp_check_filetype_and_ext()` can't validate the filetype, we now return
`false` for ext/MIME values.

Merges [39831] to the 4.4 branch.
