Documentation: real-time: Add kernel configuration guide

Browse source

Add a configuration guide for real-time kernels.

List all Kconfig options that are recommended to be either enabled or
disabled.  Explicitly add a table of contents at the top of the document,
so that all the options can be seen in a glance.

Whenever appropriate, link to other kernel guides; e.g. cpuidle, cpufreq,
power management, workqueues, and no_hz.

Add a summary at the end of the document warning users that there is no
"one size fits all solution" for configuring a real-time system.
