gcc-plugin: update gcc-common.h for gcc-13 

Backport this kernel commit to kpatch's version of gcc-common.h:

commit e6a71160cc145e18ab45195abf89884112e02dfb

    gcc-plugins: Reorganize gimple includes for GCC 13

    The gimple-iterator.h header must be included before gimple-fold.h
    starting with GCC 13. Reorganize gimple headers to work for all GCC
    versions.

Note that we can't directly copy the gcc-plugin headers from the kernel
as has it has dropped gcc-4.9 and older support since v5.16.  Distros
like rhel-7 still use gcc-4.8, so manually cherry pick changes into the
kpatch tree.
