Pull sched_ext tree reorg from Tejun Heo:
 "Pure source reorganization with no functional change:

   - the kernel/sched/ext* files move into a new kernel/sched/ext/
     subdirectory

   - the headers and sources are made self-contained so editor tooling
     can parse each file on its own"

* tag 'sched_ext-for-7.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext:
  sched_ext: Move shared helpers from ext.c into internal.h and cid.h
  sched_ext: Make kernel/sched/ext/ sources self-contained for clangd
  sched_ext: Move sources under kernel/sched/ext/

idle.c and cid.c are included into build_policy.c together with ext.c and
use helpers that ext.c defines. Because the helpers live in ext.c, the two
files can not parse as standalone units and clangd reports errors in them.

Move the helpers to the headers they belong to. The op-dispatch macros and
helpers plus scx_parent() to internal.h, and scx_cpu_arg()/scx_cpu_ret() to
cid.h. No functional change. idle.c and cid.c now parse clean standalone.

The sources under kernel/sched/ext/ build as a single translation unit:
build_policy.c includes the source files and headers. An LSP/clangd editor
parses each as a standalone unit, sees no types, and reports a flood of
errors.

Give each header its dependencies and include guard, and have each source
include the headers it uses.

ext.c, arena.c and the ext headers now parse clean standalone. idle.c and
cid.c still reference a few macros and helpers defined in ext.c. The next
patch moves those to shared headers.

A comment in kernel/irq/msi.c incorrectly refers to
CONFIG_PCI_MSI_ARCH_FALLBACK instead of CONFIG_PCI_MSI_ARCH_FALLBACKS.
Correct it.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
