openharmony-standard-3.0: Update source repositories to v3.0.1

This updates the OpenHarmony source repositories to version 3.0.1.

Only the patch for third_party/icu needed some rework and the removal of
compiler option '-Wno-error=implicit-float-conversion' for gcc.

This also set OPENHARMONY_VERSION_FULL to 3.0.1 the openharmony-3.0
distro override.
