[PATCH v5 0/5] drm/vkms: Switch all vkms object to DRM managed objects

To simplify the memory managment this series replace all manual drm
object managment by drm-managed one. This way the VKMS code don't have to
manage it directly and the DRM core will handle the object destruction.

No functional changes are intended in this series.

PATCH 1/5: Migrate connector managment to drmm
PATCH 2/5: Migrate encoder managment to drmm
PATCH 3/5: Migrate connector management to drm
PATCH 4/5: Introduce drmm_writeback helpers
PATCH 5/5: Migrate writeback connector management to drm

For the drmm_writeback helpers, you can find some discussions here [3].

Changes in v3:
- As suggested by Maxime, split the managed and the dynamic allocation
parts in different series
- To reduce the diff in this series, extract the "remove crtc index" part,
see https://lore.kernel.org/all/20240906-vkms-remove-index-v1-1-3cfedd8ccb2f@bootlin.com/
