Subject: [PATCH] Add bare metal support to Nuvoton targets

Modify `targets.json` to configure bare metal for the following targets:
NUMAKER_IOT_M252, NUMAKER_IOT_M263A, NUMAKER_IOT_M487, NUMAKER_PFM_M487,
NUMAKER_PFM_NUC472. Add target link interface between nuvoton library
and mbed-cmsis-cortex-m.
