  [clang][Darwin] Remove legacy framework search path logic in the frontend (#75841)

This removes a long standing piece of technical debt. Most other
platforms have moved all their header search path logic to the driver,
but Darwin still had some logic for setting framework search paths
present in the frontend. This patch moves that logic to the driver
alongside existing logic that already handles part of these search
paths.

This is intended to be a pure refactor without any functional change
visible to users, since the search paths before and after should be the
same, and in the same order. The change in the tests is necessary
because we would previously add the DriverKit framework search path in
the frontend regardless of whether we actually need to, which we now
handle correctly because the driver checks for ld64-605.1+.

Fixes #75638
