ANDROID: trusty: Rename transfer memory to lend

Renaming trusty_transfer_memory to trusty_lend_memory allows Trusty
to export memory operation like share, lend, reclaim and use common
code for memory share and lend operations.

Define TRUSTY_DEFAULT_MEM_OBJ_TAG as 0 and use that in existing calls.
