[PATCH v2 2/2] lib/string: shrink lib/string.i via IWYU

[tanzirh]

This diff uses an open source tool include-what-you-use (IWYU) to modify
the include list changing indirect includes to direct includes.
IWYU is implemented using the IWYUScripts github repository which is a tool that is
currently undergoing development. These changes seek to improve build times.

This change to lib/string.c resulted in a preprocessed size of
lib/string.i from 26371 lines to 5259 lines (-80%) for the x86
defconfig.
