zephyr: Add CONFIG_ERPC_ENDPOINT_NAME

ERPC_ENDPOINT_NAME must be the same for both local and remote sides.
Currently, it is set as a local parameters in different places which
make it difficult to be aligned between sides.

Add a Kconfig for this so that it can be used easily for both remote and
server applications.
