Also add an API to inhibit the kernel thread from being used, and make MetaRenderDeviceEglStream inhibit the kernel thread from being used if it's active. The reason for this is that the MetaRenderDeviceEGlStream is used when using EGLStreams instead of KMS for page flipping. This means the actual page flipping happens as a side effect of using EGL/OpenGL, which can't easily be done off thread. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2777>
