Hi!

Here is a fix to jdk.jdi that fixes reproducible build for Windows. The idea of 
the fix is to re-use value of --with-hotspot-build-time option to generate 
deterministic timestamp exactly like it's done to hotspot component.

Verification (Windows-10/MSVS-2019): ```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" 
--with-extra-cxxflags="/experimental:deterministic"```

Regression (Windows-10/MSVS-2019): ```bash ./configure 
--with-boot-jdk=c:/work/boot-jdk/jdk-18 --with-debug-level=fastdebug```
