Kareem Ergawy 2cc8734c45 [flang][fir] Basic lowering fir.do_concurrent locality specs to fir.do_loop ... unordered (#138512) ...

Extends lowering `fir.do_concurrent` to `fir.do_loop ... unordered` by
adding support for locality specifiers.

In particular, for `local` specifiers, a `fir.alloca` op is created
using the localizer type. For `local_init` specifiers, the `copy` region
is additionally inlined in the `do concurrent` loop's body.
