Original CL Desc ----------------------------------------------------------------- [Mode Manager] Fix some singleton startup pattern that was allocating at incorrect timings to speculatively fix some allocate on shutdown crash(es) Also move some of the global access to the level editor mode manager to pipe through the level editor where there were some early accessors on startup. #jira UE-213541 #rb patrick.enfedaque ross.smith2 #p4v-cherrypick 33703049 [CL 33736118 by brooke hubert in ue5-main branch]
