Fix sloppy base64 acceptance of some multibyte characters
The base64 encoding functions incorrectly accepted some multibyte
characters; stop doing that (bug#52670).
* src/fns.c (base64_encode_1): Reject all multibyte characters.
* test/src/fns-tests.el (fns-tests-base64-encode-string)
(fns-test-base64url-encode-region)
(fns-test-base64url-encode-string): Add tests.
* doc/lispref/text.texi (Base 64): Rephrase outdated manual text.
* etc/NEWS: Add a notice.
