Boost `1.88.0` introduced a feature [^1] that makes use of the Windows API, but it
uses API functions that are only available with `PSAPI_VERSION >= 2` and
Windows VISTA only supports `PSAPI_VERSION == 1`. Actually, that new feature
can also be disabled by setting the `BOOST_STACKTRACE_DISABLE_OFFSET_ADDR_BASE`
macro, but since it seems to be a useful feature and isn't even disabled by default,
we can just drop it that ancient Windows version instead of disabling it.
