Add a dashboard component that displays RMM memory

[pentschev]

This is an overhaul of #5740 , primarily updating colors as requested in that PR's review, which adds a visualization that provides a bit more information than the current GPU memory utilization plot. It also shows the amount of GPU memory being managed by RMM, and in the case of a RMM pool, the amount of pool memory actually used:

There are green bars with varying opacity representing from left to right: the amount of memory used from the RMM pool, the amount of free memory in the RMM pool and the amount of memory allocated outside of the RMM pool.

Thanks for pushing this forward @pentschev. This looks good to me.

I hope you don't mind @pentschev but I've pushed a commit to fix up the linting and tweak an extra line. I'll leave this to sit for a bit in case other folks want to weigh in, but otherwise, I intend to merge this tomorrow.

Test failures appear unrelated. Merging.
