Fix various issues in unsafe_proxy (#82326) (#82330)

- Use str/bytes directly instead of text_type/binary_type
- Fix AnsibleUnsafeBytes.__str__ implementation
- Fix AnsibleUnsafeBytes.__format__ return type
- Remove invalid methods from AnsibleUnsafeBytes (casefold, format, format_map)
- Use `chars` instead of `bytes` to match stdlib naming
- Remove commented out code

(cherry picked from commit 59aa0145d2)
