Correct the vCard 3 parameter parser so quoted parameter values are
consumed according to the MIME-DIR grammar instead of failing
immediately on the opening double quote.
The fix explicitly advances past the opening quote, reads the quoted
qsafe-char sequence, and strips the surrounding quotes from the returned
parameter value. Unquoted parameter handling is unchanged.
Add private parser coverage for quoted parameter values and quoted
values containing commas, plus a public regression test showing that
quoted LANGUAGE and TYPE parameters are accepted by the vCard 3 parser.
