[Feature] Button for clearing caches

[Kingproone]

pacman -Sc yay -Sc (this incorporates pacman -Sc)

The different directories cleaned by the commands:

Other wrappers may have different options for it, and would need to be added, since for example yay keeps it's own cache that likes to build up over time.

Until the update size doesn't have 6 figures, I feel it has space.

• since this is only a problem when using the smallest layout combined with a lot of updates, it is probably fine to have the rightmost few characters be truncated, otherwise 2 possible solutions
  1. The icon on the left could be removed to make space for it. (my vote is for this)
  2. Rounding the update size to a full number could be a solution as well.

I also found that yay can clean unneeded dependencies with -Yc, this clears additional things compared to orphan cleanup, a quick show of it:
