build: update to latest MDC canary and disable slider (#20054)

Updates to the latest canary version and temporarily disables the MDC-based slider. We have to disable the slider, because MDC have introduced a completely new implementation that will take some work to reintegrate into our current slider and we don't want our CI to fail until then.

I went with this approach of disabling the slider where it's basically a no-op, because we can't simply exclude the build target without modifying a ton of shared files which will be hard to clean up once we start to actually implement it.
