Documentation/protection-keys: Clean up documentation for User Space pkeys
...
The documentation for user space pkeys was a bit dated including things
such as Amazon and distribution testing information which is irrelevant
now.
Update the documentation. This also streamlines adding the Supervisor
pkey documentation later on.

docs: move protection-keys.rst to the core-api book
...
This document is used by multiple architectures:
$ echo $(git grep -l pkey_mprotect arch|cut -d'/' -f 2|sort|uniq)
alpha arm arm64 ia64 m68k microblaze mips parisc powerpc s390 sh sparc x86 xtensa
So, let's move it to the core book and adjust the links to it
accordingly.
