[client] egl: retain damage until texture is drawable

Browse Source 
Treat a failed desktop texture bind as an incomplete render so full target
restoration remains latched until a frame can actually be drawn.

Carry retired damage into the pending record when the drawable texture does
not contain it, closing the publication gap between texture slots and their
matching damage metadata.
