feat: Added optional fips_compliant field to WixConfig

[JakenHerman]

This allows users to set the -fips flag at the tauri.windows.conf.json level instead of using the environment variable TAURI_BUNDLER_WIX_FIPS_COMPLIANT. To me this makes for smoother FIPS-compliant builds.

As with other environment variables that also have config fields, the environment variable will override whatever is set in the config.

Per PR Guidelines:

Ideally you should open a suggestion issue first and have it greenlighted before working on it:

I've bumped tauri-utils to v2.5.1 and provided a markdown file in the .changes directory.
