Add "arch" struct field to repository_os

This new field provides access to the Java "os.arch" property to
repository rules, which previously had to rely on uname (Unix) or
additional env variables (Windows) to detect the architecture.

This also fixes a small issue in the existing implementation of
repository_ctx.os.name, which should use the root locale when converting
the value of the "os.name" property to lowercase.

Existing sites of manual architecture detection in shipped repository
rules as well as redundant calls to lower() on the value of
repository_ctx.os.name are cleaned up.

Fixes #14685

Closes #14738.
