Interface: Move the tz_context.h from app to interface
The APIs in tz_context.h are for NS usage, so it should belong to interface. And the implementations source files should include it. It should be exported when building as well. Change-Id: Ia6970b3e0a6e492411ec1b70783c1bdd555df8b9 Signed-off-by: Kevin Peng <kevin.peng@arm.com>
