validates |italic= assigned values.
When |italic= is set and has an acceptible assigned value, return the matching css font-style property value or,
for the special case 'default', return nil.
When |italic= is not set, or has an unacceptible assigned value, return nil.
The return value nil causes the calling lang or lang_xx function to set args.italic according to the {{lang}} or
{{lang-xx}} template's defined default ('normal' for {{lang}}, 'normal' or 'italic' for {{lang-xx}} depending on
the individual template's requirements) or to the value appropriate to |script=, if set.
Accepted values and the values that this function returns are are:
nil - when |italic= absent or not set; returns nil
default - for completeness, should rarely if ever be used; returns nil
yes - force args.text to be rendered in italic font; returns 'italic'
no - force args.text to be rendered in normal font; returns 'normal'
unset - disables font control so that font-style applied to text is dictated by surrounding markup; returns 'inherit'
