Subject: [PATCH] ISSDK-1876: Skip x-createOnly defaults in NewXxx and
 NewXxxWithDefaults Go constructors

Properties marked x-createOnly must not be injected into the struct by
the generated constructors -- the Intersight API rejects them in POST if
they arrive with a stale default value (e.g. ServerFamily='All' on
server.Profile / server.ProfileTemplate).

Add {{^vendorExtensions.x-createOnly}} guards around the default-value
assignment blocks in both New{{classname}} and New{{classname}}WithDefaults
in model_simple.mustache, mirroring the existing {{^isReadOnly}} pattern.
