Subject: [PATCH 10/15] Pass HIP library directly and refactor
Summary:
Currently we pass `-L` and `-l` to get the HIP library. Because we are
attached to a single HIP installation it's far better to pass it by
filename. This is because the `-L` could be out of order with other user
libraries and those could override it. If someone uses HIP with a
specific ROCm installation they most likely want that library, otherwise
incompatibilities can occur. This is still overridable with command line
flags if users want to pass a different one for some reason.
This PR also refactors the handling to be more generic for future
additions.
