Build: Unify TF-M version setting

In each release, two TF-M version settings, one in CMake and the other
one in tfm_version.h, shall be both updated. Either one may be missed in
release.

This commit unifies TF-M version settings. Only the version in root
CMakeLists.txt shall be updated. The version used in source code will be
automatically updated during build.
