  Log Message:
  -----------
  [Flang] LoongArch64 support for BIND(C) derived types in mabi=lp64d. (#117108)

This patch:
- Supports both the passing and returning of BIND(C) type parameters.
- Adds `mabi` check for LoongArch64. Currently, flang only supports
`mabi=` option
set to `lp64d` in LoongArch64, other ABIs will report an error and may
be supported
  in the future.
