[SurfaceFlinger] support EGLImage management in BLAST
This mirrors a performance optimization for BufferQueueLayers where
EGLImages were allocated in onFrameAvailable. Here when buffers are
passed over to SurfaceFlinger in a transaction, an EGLImage is also
created for that buffer.
This is critical for reducing jank when operating in higher refresh
rates, as eglCreateImageKHR can take long enough for frames to miss.

Test: systrace of chrome in landscope orientation caches properly
