Subject: [PATCH] Always include target CPU architecture in About dialog
 Version Information

...not just for Windows.  This information is occasionally useful also on other
platforms that can run executables targeting different CPU architectures (like
Linux x86 and x86-64, or macOS Aarch64 and x86-64), e.g. when trying to track
down why a bug reporter's system doesn't find a JRE matching the architecture of
their LibreOffice installation.

For simplicity, use the existing _ARCH bootstrap variable, even if its values
differ from the hardcoded "x64" and "x86" that have been used here so far.
