[jdk11u-dev] RFR: 8341424: GHA: Collect hs_errs from build time failures

[Antonio Vieiro]

Backport of [JDK-8341424](https://bugs.openjdk.org/browse/JDK-8341424) and companion [JDK-8342704](https://bugs.openjdk.org/browse/JDK-8342704)

This collects hs_errs when they happen with GitHub Actions, which may be useful during reviews.

Low risk, as this affects GHA actions only. GHA builds and tests run correctly.
