Subject: [PATCH v3 0/2] shrink lib/string.i via IWYU

This patch series changes the include list of string.c to minimize
the preprocessing size. The patch series intends to remove REPEAT_BYE
from kernel.h and move it into its own header file because
word-at-a-time.h has an implicit dependancy on it but it is declared
in kernel.h which is bloated.

---

---
Changes in v3:
- Moved REPEAT_BYTE out of kernel.h and into wordpart.h.
- Included wordpart.h where REPEAT_BYTE was necessary.
- Link to v2: https://lore.kernel.org/r/20231214-libstringheader-v2-0-0f195dcff204@google.com

Changes in v2:
- Transformed into a patch series
- Changed asm inclusions to linux inclusions
- added a patch to sh
- Link to v1: https://lore.kernel.org/r/20231205-libstringheader-v1-1-7f9c573053a7@gmail.com
