Turning gr_learn_resource etc. into dummy static inlines

[Lox]

Recently I did some perf recording and noticed gr_learn_resource and some other functions show up here and there where the time spent wasn't completly negligible.

I wondered if there is any harm in turning these into complete NOOPs? With the RBAC and a few other features disabled it doesn't seem to require them?

I hope the kernel will get complete LTO support sometime..

I've added this to my TODO.
