Remove IWYU pragmas

These were added as part of
d5c80ad9c07b94465d8ea62d2b6f87c30cac765e: test treewide: iwyu

Since then, Nan hasn't been very active on the project, and to my
knowledge, since the initial run, we've never used IWYU again.

clang-include-cleaner seems to work well without needing these pragmas,
and is what we're using, even if it's less useful than IWYU.

Remove all mention of IWYU.

Tested: Code compiles.
