[jdk21u-dev] RFR: 8315413: Remove special filtering of Continuation.yield0 in StackWalker

Thu Aug 28 20:08:20 UTC 2025

A clean backport of https://bugs.openjdk.org/browse/JDK-8315413.

Those special filtering is no longer needed because to be filtered methods are already marked by `@Hidden`.

Tests in this pr passed. Other jtregs are running.
