Use ASCII-8BIT paths in ActionDispatch::Static

The rack gem returns PATH_INFO as an ASCII-8BIT encoded string but it
was being converted to US-ASCII by the match? method because it was
calling Rack::Utils.escape_path. To prevent incompatibile encoding
warnings use ASCII-8BIT strings for the root path and let Ruby handle
any filename encoding conversion.

Fixes #32294, Closes #32314.
