The default resource group and its files are created during kernel
init time. Upcoming changes will make some resctrl files optional
based on a mount parameter. If optional files are to be added to the
default group based on the mount option, then each new file needs to
be created separately and call kernfs_activate() again.

Create all files of the default resource group during resctrl
mount, destroyed during unmount, to avoid scattering resctrl
file addition across two separate code flows.
