Problem:  filetype: hip files are not recognized
Solution: Detect *.hip files as hip filetype, include filetype, syntax
          and indent plugins, update makemenu.vim and synmenu.vim (Young)

Round out HIP (Heterogeneous-compute Interface for Portability) support
to mirror the existing CUDA files:

- autoload/dist/ft.vim: detect the ".hip" extension as filetype "hip"
- ftplugin/hip.vim: behave like C++ by sourcing ftplugin/cpp.vim
- indent/hip.vim: use cindent, like indent/cuda.vim
- makemenu.vim / synmenu.vim: add a Syntax menu entry

The syntax/hip.vim file already sources syntax/cpp.vim and adds the
HIP-specific keywords, matching syntax/cuda.vim.
