[libclc] [libclc] [cmake] Fix per-target *_convert.cl dependencies (PR #127315)

[Michał Górny via cfe-commits]

https://github.com/mgorny created https://github.com/llvm/llvm-project/pull/127315

Fix `add_libclc_builtin_set` to add an appropriate dependency to either `clspv-generate_convert.cl` or `generate_convert.cl` based on the `ARCH` argument, rather than to both unconditionally.  This fixes build failures due to missing dependencies when `clspv*` targets are not enabled.
