sotaro 3ece048a1b Bug 1829063 - Split video overlay feature of software decoded video from nsIGfxInfo::FEATURE_VIDEO_OVERLAY r=gfx-reviewers,lsalzman
Current gecko enables "software decoded video overlay" only when "hardware decoded video overlay" is enabled. On current release, "hardware decoded video overlay" is not enabled yet with non-Intel GPU, then "software decoded video overlay" is not yet enabled on release. It is not good. We want to enable "software decoded video overlay" independently from "hardware decoded video overlay". Then settings of video overlay is split between "hardware decoded video overlay" and "software decoded video overlay". Then "software decoded video overlay" could be enabled/disabled independently from status of "hardware decoded video overlay".

* settings of hardware decoded video overlay
- nsIGfxInfo::FEATURE_VIDEO_OVERLAY:
- gfx.webrender.dcomp-video-hw-overlay-win
- gfx.webrender.dcomp-video-hw-overlay-win-force-enabled
- gfxVars::UseWebRenderDCompVideoHwOverlayWin()

* settings of software decoded video overlay
- nsIGfxInfo::FEATURE_VIDEO_SOFTWARE_OVERLAY
- gfx.webrender.dcomp-video-sw-overlay-win
- gfx.webrender.dcomp-video-sw-overlay-win-force-enabled
- gfxVars::UseWebRenderDCompVideoSwOverlayWin()
