Projects exist, which do not want to use an automated formatting, but
could benefit from sorting the includes, especially to include the main
headers first in order to improve the self-consistency of headers.
While this was possible with `clang-format` for some time, it was
disabled with commit `61dc0f2b593da149a4c0cea67819cd7bdbdd50b8`. The
main reason was that it is confusing for users.
This commit enables sorting the includes more explicitly, to allow the
feature without confusing users.

Subject: [PATCH] [clang-format] Enable sorting includes although formatting
disabled
