fix: use locale-neutral Windows ACL for build data (#3887)

On localized Windows installations, `build_data_writer.ps1` could fail
when
creating the output file ACL because it used the English localized
`Everyone`
principal name.

This changes the ACL rule to use the language-neutral `WorldSid`
identity
instead, preserving the existing Everyone read permission without
depending on
the display language of Windows.

Before: German and other localized Windows installs could fail with
`IdentityMappedException` / `IdentityNotMappedException`.

After: build data generation succeeds on localized Windows installs.

Fixes #3886

Tests:
`bazelisk test //tests/build_data:build_data_test --config=fast-tests`
