Make egl surface uncurrent when being destroyed This is to workaround errors when app does below behaviors: 1) while there is a context still bound to the current rendering thread and the surface, call eglDestroySurface() 2) create a new surface eglCreateWindowSurface() 3) call eglMakeCurrent() with the surface created in step 2) 4) does work on the new surface The old surface won't be destroyed in step 1) because it was still bound by the context of the current rendering thread. When creating new surface on step 2), some hardware will return error code EGL_BAD_ALLOC, because the old egl surface is still associated with the native window. To workaround, when destroying surface, if the surface is still bound by the context of the current rendering thread, release the context and surface by passing EGL_NO_CONTEXT and EGL_NO_SURFACE to eglMakeCurrent(). The workaround is controlled by a frontend feature uncurrentEglSurfaceUponSurfaceDestroy. This feature is only enabled on vulkan and gl backends.
