renderer: set EGL_CONTEXT_RELEASE_BEHAVIOR_KHR if supported (#234)

Browse source 
EGL_CONTEXT_RELEASE_BEHAVIOR_KHR determines what happends with implicit
flushes when context changes, on multigpu scenario we change context
frequently when blitting content. while we still rely on explicit sync
fences, the flush is destroying driver optimisations.

setting it to EGL_CONTEXT_RELEASE_BEHAVIOR_NONE_KHR essentially mean
just swap context and continue processing on the next context.
