Build: Merge secure_api & sp_log_raw into tfm_sprt

This patch merges tfm_secure_api and tfm_sp_log_raw library
into tfm_sprt.
The APIs in tfm_secure_api and tfm_sp_log_raw are for Secure
Partitions usage thereforce they can naturally be moved to tfm_sprt
as tfm_sprt is intended for Secure Partition usages.

This patch also changes tfm_sprt to publicly link psa_interface.

With these changes, Secure Partition libraries need to link a single
tfm_sprt for all interactions with the framework.

This patch also removes some unnecessary links.
