[jdk21u-dev] RFR: 8331352: error: template-id not allowed for constructor/destructor in C++20

[Jan Kratochvil]

It is needed to build OpenJDK-21 on Fedora 40 x86_64 (gcc-14.1.1-1.fc40.x86_64).
It needs all of [JDK-8328997](https://bugs.openjdk.org/browse/JDK-8328997) ([backport](https://github.com/openjdk/jdk21u-dev/pull/564)), [JDK-8331352](https://bugs.openjdk.org/browse/JDK-8331352) (this [backport](https://github.com/openjdk/jdk21u-dev/pull/565)) and [JDK-8324243](https://bugs.openjdk.org/browse/JDK-8324243) ([backport](https://github.com/openjdk/jdk21u-dev/pull/566)).
Git cherry-pick was clean.
