zephyr: migrate signature type to Kconfig Handle the CONFIG_BOOT_SIGNATURE_TYPE_xxx values in Zephyr's mcuboot_config.h by converting them into the platform-agnostic MCUboot definitions. This requires some changes to the way the release test Makefile is structured, since Kconfig symbols cannot be set from the command line. Instead, use the OVERLAY_CONFIG feature of the Zephyr build system, which allows specifying extra fragments to merge into the final .config. (This is an orthogonal mechanism to setting CONF_FILE; it is used by Zephyr's CI script sanitycheck to add additional fragments, so it's appropriate for use by MCUboot's testing scripts as well.) We additionally need to move to a single prj.conf file due to a dependency issue. We can no longer determine CONF_FILE from the signature type, since that is now determined from the final .config or autoconf.h, which is a build output that depends on CONF_FILE. To move to a single prj.conf: - delete prj-p256.conf and adjust prj.conf to serve both signature types - add a top-level mbedTLS configuration file which dispatches to the right sub-header depending on the key type - as a side effect, have the simulator pick the right config file depending on the case This fixes and cleans up quite a bit of the signature type handling, which had become something of a mess over time. For example, it fixes a bug in ECDSA mode's configuration that wasn't actually selecting config-asn1.h, and forces the simulator to use the same mbedTLS configuration file as builds for real hardware. Finally, we also have to move the mbedTLS vs. TinyCrypt choice into mcuboot_config.h at the same time as well, since CMakeLists.txt was making that decision based on the signature type.
