  Reland "[lldb][DWARF] Remove object_pointer from ParsedDWARFAttributes (#145065)" (#145126)

This reverts commit 877511920dcf36463e06746d626e8876583a6abd.

This fixes the `TestObjCInBlockVars.py` LLDB API test.

The issue was that `GetCXXObjectParameter` wouldn't deduce the object
parameter of Objective-C method definitions correctly. In DWARF those
don't have a `DW_AT_specification` (so no link back to a DeclContext
that is a class type). The fix is to only check the validity of the
DeclContext DIE *if* no `DW_AT_object_pointer` exists on the DIE. If
`DW_AT_object_pointer` does exist, we should just always use that as the
object_parameter.
