Creating the node_modules folder when the packages are already
downloaded can take a bit of time and not knowing what is going on can
be confusing. It's better to show a progress bar.
This is implemented in such a way that it should still allow processes
to go through when a file lock wasn't properly cleaned up and the OS
hasn't released it yet (but with a 200ms-ish delay).
Closes#18039
This PR adds the concept of a global `DrawThread`, which can receive
multiple renderers to draw information on the screen (note: the
underlying thread is released back to tokio when it's not rendering). It
also separates the concept of progress bars from the existing "draw
thread". This makes it trivial for us to do stuff like show permission
prompts and progress bars at the same time in the future.
The reason this is global is because the process' tty stderr is also a
global concept.
