  -----------
  [HIP] Support managed variables using the new driver (#123437)

Summary:
Previously, managed variables didn't work in rdc mode using the new
driver because we just didn't register them. This was previously ignored
because we didn't have enough space in the current struct format. This
patch amends that by just emitting a struct pair for the two variables
and using the single pointer.

In the future, a more extensible entry format would be nice, but that
can be done later.
