Instead of only escaping '\', '', and ';', all non-alphanumeric values are escaped. Backslashes are doubld and other characters are encoded as hex. The previous version would pass invalid characters through unescaped, including OSC sequences. Although that no longer is allowed, this iteration does not yet enforce particular (e.g. utf-8) encoding and will still misbehave on multibyte sequences.

This implements the string escaping scheme documented for the "E" (executed) and "P" (property KV) codes. This is "pure"
zshand relies on no external utilities.Although currently the only "required" escapes are backslash, semicolon,
\a, and perhaps newlines, this conservatively escapes all non-alphanumeric characters.Backslashes are doubled, non-alphanumerics are hex-escaped.

Caveat
Unaddressed here, but more plain to see than in the other shells, is that the encoding of multibyte codepoints is not currently well-defined by the escaping scheme. This chooses to encode as UTF-8 in order to make them byte-representable at all. Regardless,
shellIntegrationAddon.tsseverely mishandles the interpretation of escapes anyway, even in the ASCII range, so the point is slightly moot.
