[PATCH] MAINTAINERS: add headers and doc to SCHEDULER

[Lukas Bulwahn]

Various files in include/linux/sched/ and include/uapi/linux/sched/ are
identified as part of THE REST according to MAINTAINERS, but they really
belong to SCHEDULER.

Add those headers and Documentation to the SCHEDULER section.

This was identified with a small script that finds all files belonging to
THE REST according to the current MAINTAINERS file, and I investigated
upon its output.

RFC v1: https://lore.kernel.org/lkml/20200308174931.9118-1-lukas.bulwahn@xxxxxxxxx/
  - no feedback.

RFC v2: https://lore.kernel.org/lkml/20200413112603.5257-1-lukas.bulwahn@xxxxxxxxx/
  - RFC v1 does not apply after reordering MAINTAINERS, i.e., commit 4400b7d68f6e
    ("MAINTAINERS: sort entries by entry name") and commit 3b50142d8528
    ("MAINTAINERS: sort field names for all entries").
  - does not need to reorder entries anymore.
  - applies cleanly on v5.7-rc1
  - no feedback.

v1:
  - rebased to v5.9-rc3
  - minor wording: s/SCHEDULER entry/SCHEDULER section/
  - increase recipients to all scheduler maintainers to get some feedback
