[nrf fromlist] modules: tf-m: Add syscall header dependency for TF-M

Zephyr generates the system call headers using CMake custom
targets and various scripts. Some platforms, like the Nordic onces,
reuse some files located in Zephyr inside the TF-M build as well.
Because of this the generated Zephyr headers needs to exist before
TF-M starts the build process in order to succeed.

This adds a dependency to make sure TF-M starts building after the
Zephyr custom command which generates the system call headers is
executed.
