tee_client_api: deprecate two TEE_ERROR_* macros not in the specifica…

…tion

TEE_ERROR_EXTERNAL_CANCEL and TEE_ERROR_STORAGE_NO_SPACE are not part
of the specification [1]. TEEC_ERROR_EXTERNAL_CANCEL and
TEEC_ERROR_STORAGE_NO_SPACE should be preferred instead.

Add a message in the description to deprecate these two macros, but
keep them for backward compatibility.
