[jdk18u] RFR: 8287894: Use fixed timestamp as an alternative of __DATE__ macro in jdk.jdi to make Windows build reproducible

[Alexey Pavlyutkin]

Hi!

Here is a backport of 8287894 that fixes reproducible debug build for Windows. The original patch applied cleanly.

Verification (Windows10/MSVS2019): `bash ./configure --with-boot-jdk=c:/work/boot-jdk/jdk-18 --with-debug-level=fastdebug --with-hotspot-build-time="6/7/2022 2:35pm" --with-extra-cflags="/experimental:deterministic"`
