The EdidWrapper lifecycle was previously managed by DrmConnector,
meaning the EDID parser was initialized when the connector was created.
This approach fails for physical connectors where a display is not
attached at boot, as no EDID blob is available to parse.
When a display was subsequently hot-plugged, the system would fall back
to a generic EdidWrapper. This provided incorrect or default display
properties to userspace, causing critical bugs such as:
* Incorrect DPI calculations, leading to improperly scaled UI in
Android.
* Inability to detect HDR capabilities or supported color modes.
This change moves the ownership and lifecycle management of the
EdidWrapper to HwcDisplay. By creating the parser only when a display is
actually connected, we ensure that the correct EDID is always parsed,
making hot-plug functionality work as intended.
