[Testing] adding cacule scheduler

[Peter Jung]

Im using this scheduler on my desktop and have a much better experience in general responsive's and also under heavy load still smooth runing desktop.
Ive tested to get the scheduler running on arm devices and it worked great so far, ive tested armv7h and aarch64.
This needs more tested from users which are using the arm device as daily driver.

Patches can be found here:

https://github.com/hamadmarri/cacule-cpu-scheduler

if building for 32-bit arm devices, the 32-bit converter is also needed.

Following config options needs to be added to the default defconfig:

CONFIG_FAIR_GROUP_SCHED=y
CONFIG_CACULE_SCHED=y
