  [cmake] Ensure that LINK_LIBS are dependencies for object library targets

In MLIR, it is common for automatically generated headers to be included
in many places.  To avoid tracking these dependencies explicitly in
cmake, they are treated as part of a library which 'owns' the generated
header.  Users of the generated header link against the owning library.
However, object libraries don't actually 'link', so this dependence gets
lost.  This patch adds an explicit dependence for these generated headers
when creating object library targets to ensure that generated headers
are appropriately generated
