 Media: Optimize Imagick settings for quality and filesize

 - Resamples and sharpens larger images before resize.
 - Uses imagick::FILTER_TRIANGLE for a smoother resize.
 - Introduces `WP_Image_Editor_Imagick::thumbnail_image()` protected method
 to efficiently resize images. Similar to the functionality of Imagick's
 - Introduces `WP_Image_Editor_Imagick::strip_meta()` protected method and
 `image_strip_meta` filter that, by default, strip image profiles to reduce
 file size, while leaving color profiles intact.
