More thread safety in ES2 & EGL APIs

Tweak ContextPtr to handle move construction/assignment correctly.
This was overlooked when I made the last minute change to use explicit lock/unlock.

Tweak LockGuard to allow construction from ptr to MutexLock, and behave
correctly if mutex == nullptr. This is required because the locking
machinery for EGL is /outside/ the error generation for bad EGLDisplay.

Add 'Big EGL Lock' around most of the EGL API
