backend/drm: generate CVT reduced modes
The Coordinated Video Timings (CVT) spec [1] defines two types of timings: the "CVT standard CRT" timings and the "CVT reduced blanking" timings (see section 3.6). The standard CRT timings include pauses in the video stream to allow CRT displays to reposition their electron beam at the end of each horizontal scan line [2]. While this was desirable a few decades ago, nowadays we can just generate a CVT reduced blanking timing by default. wlroots users can still set full custom DRM modes via wlr_drm_connector_add_mode.
