[jdk17u-dev] RFR: 8353309: Open source several Swing text tests

Thu Sep 11 23:59:07 UTC 2025

Backporting JDK-8353309: Open source several Swing text tests. Adds five swing text related tests. Ran GHA Sanity Checks, local Tier 1 and 2, and new tests directly. Patch is not clean, but trivial fix: there's a typo in one of the tests addressed by [JDK-8359418](https://bugs.openjdk.org/browse/JDK-8359418) that I've included here. Backporting for parity with Oracle.
