Roman Gilg 7459aabcac Dmabuf recovery on EGL reset
Summary:
The EGL platform might go away at any time through reconfiguration or because
of a graphic error. KWin then resets the graphics. The dmabuf implementation
must respect that and recover from a graphics reset by recreating all EGL
images for existing buffer.

This assumes that we won't change our graphics API mid-session and that
supported plane and modifier configuration stays constant.

In practise we remember all current dmabufs in a single map and only remove
them if the client did destroy the resource.

BUG: 411980
CCBUG: 413403
FIXED-IN: 5.17.2

Test Plan: Applied screenedge configuration without crash.
