Fix `buffer.transcode()` for transcoding from single-byte character encodings to UCS2. These would previously perform out-of-bounds reads due to an incorrect `sizeof()` expression. Fixes: nodejs#9834

There was a problem hiding this comment.
The other instances of sizeof in this file use **destbuf or UChar. I’m fine with using destbuf[0] everywhere but right now I wouldn’t want to add more confusion here.

@addaleax this is not landing cleanly on v6.x or v4.x There are some other commits that need to get pulled for this to land cleanly, should we backport? |

@thealphanerd This affects a feature added in #9038, which exists only in v7. I’m removing the lts-watch labels here and left a comment over there, let me know if you need anything else :) |
