Simon Ser d208d87566 drm: introduce CLOSEFB IOCTL ...

This new IOCTL allows callers to close a framebuffer without
disabling planes or CRTCs. This takes inspiration from Rob Clark's
unref_fb IOCTL [1] and DRM_MODE_FB_PERSIST [2].

User-space patch for wlroots available at [3]. IGT test available
at [4].

v2: add an extra pad field just in case we want to extend this IOCTL
in the future (Pekka, Sima).
