vim-patch:9.2.0235: filetype: wks files are not recognized (#38451)

Problem:  filetype: wks files are not recognized.
Solution: Detect *.wks, *.wks.in and *.wks.inc as wks filetype,
          include a filetype and syntax plugin (Anakin Childerhose)

The OpenEmbedded Image Creation tool, `wic` uses wic kickstarter files
to define image partition and bootloader layouts.
wks files can end with .wks, .wks.in for templated wks files, and
.wks.inc for including in other .wks files.

The autocmd for *.wks.inc needs to come before *.inc in
runtime/ftdetect.vim
