[jfx17u] RFR: 8315873: [GHA] Update checkout and cache action to use v4

Wed Mar 5 07:46:31 UTC 2025

mainly clean backport of https://github.com/openjdk/jfx/commit/6ec588c5635964769b354bce37e68d7a6c00985a (JDK-8315873)

Reason for being non-clean:
* we already applied 8350437
* we don't have aarch64-mac
* we don't have TEST_ONLY in build.gradle
