Fix cuda_fp16.h not found issue

[lockshaw]

Description of changes:

On machines where the cuda headers were not automatically being searched, a build error would result in utils/fp16.h. This fixes that by explicitly adding the found cuda include directories to the requirements of utils.

Before merging:

• Did you update the flexflow-third-party repo, if modifying any of the Cmake files, the build configs, or the submodules?

@lockshaw Should this PR also fix the build error?
