improvement(fluid-build): Add a spinner with additional info for incremental task checks (#23282)

Adds a CLI spinner to display a little more feedback when loading the
build graph and checking incremental tasks. Currently fluid-build just
sits there for awhile and looks like it's hung. There is more that we
could do, but this is a step in the right direction.
