Fix ExternalImageTarget EGLImage race Race may happen when ExternalImageTarget EGLImage is destroyed while its GLES Texture/Renderbuffer target is modified/destroyed. Fixed by providing `egl::Image` with `egl::ContextMutex` even when `context` is `nullptr`. This CL also changes `SharedContextMutex` merging rules when `mRank` is equal - now priority goes to the `lockedMutex`. This is done to prevent unnecessary `mRoot` update of Context mutex when merging with `egl::Image` only mutex.
