Previously, the yuv_convert APIs internally asserted the success of the underlying libyuv API calls. This patch modifies the yuv_convert APIs to return the results of these calls instead of silently asserting them. While the assertions are temporarily removed, they will be reintroduced in appropriate locations in subsequent patches. Differential Revision: https://phabricator.services.mozilla.com/D216186
