Bug 1732115 - Part 1. Add swizzling support for reorienting by row. r=tnikkel
This is a new swizzle operation which allows us process a reorientation row by row into its new orientation. This will be used in a later part in the series in the image decoding pipeline. Differential Revision: https://phabricator.services.mozilla.com/D126379
