This rounds out HIP (Heterogeneous-compute Interface for Portability) support so
it mirrors the existing CUDA runtime files. syntax/hip.vim already existed
(sourcing syntax/cpp.vim plus HIP-specific keywords, like syntax/cuda.vim),
but the surrounding pieces were missing.

Changes, each mirroring its CUDA counterpart:

autoload/dist/ft.vim: detect the .hip extension as filetype hip
(next to the existing .cu/.cuh → cuda entries).
ftplugin/hip.vim (new): behaves like C++ by sourcing ftplugin/cpp.vim,
mirroring ftplugin/cuda.vim.
indent/hip.vim (new): uses cindent, mirroring indent/cuda.vim.
makemenu.vim / synmenu.vim: add a Syntax menu entry under HIJK.HIP.

The synmenu.vim change is a minimal single-line insert rather than a full
regeneration, to keep the diff limited to HIP. (A make menu regeneration also
renumbers an unrelated pre-existing duplicate priority in the C section.)

Verified with a locally built Vim on a real .hip file: filetype resolves to
hip, cindent is set, the C++ ftplugin chain applies (e.g. commentstring),
and HIP keywords highlight correctly (__global__ → StorageClass,
hipError_t/dim3 → Type, hipSuccess → Constant).
