swtpm_setup: Comment flags for storage primary key and deprecate --create-spk

Comment the flags used for creating the storage primary key.
Deprecate the --create-spk option since it may create an RSA-3072 key
and it creates a NIST P384 instead of NIST P256, both of which users may
not expect and know how to use.
