[Vcode2407]

When a carrier sends two tracestate fields, such as bar=baz followed by foo=bar, the propagator currently drops the second field. Read all values through TextMapGetter.getAll() and pass them to the existing parser in the order received, as required by W3C Trace Context.

The regression test fails on main and passes with this change. All 539 API module tests and both Checkstyle tasks passed. The existing extraction benchmark for carriers without tracestate measured 185.52 ± 53.72 ns/op on JDK 25 (one thread, one fork, 15 measurement iterations).
