  [CodeExtractor] Allow to use 0 addr space for aggregate arg (#66998)

The user of CodeExtractor should be able to specify that
the aggregate argument should be passed as a pointer in zero address
space.

CodeExtractor is used to generate outlined functions required by OpenMP
runtime. The arguments of the outlined functions for OpenMP GPU code
are in 0 address space. 0 address space does not need to be the default
address space for GPU device. That's why there is a need to allow
the user of CodeExtractor to specify, that the allocated aggregate parameter
is passed as pointer in zero address space.
