gfapi: 'glfs_h_creat_open' - new API to create handle and open fd

Right now we have two separate APIs, one
- 'glfs_h_creat_handle' to create handle & another
- 'glfs_h_open' to create a glfd to return to application

Having two separate routines can result in access errors
while trying to create and write into a read-only file.

Since a fd is opened even during file/directory creation,
introducing a new API to make these two operations atomic i.e,
which can create both handle & fd and pass them to application
