If 'mbcs' is Windows-only, then why does it appear in the
list of registered codecs in encodings.aliases.aliases on
the Linux platform? Shouldn't it not be registered on other
platforms?

UTF-8 is an MBCS encoding in that is is a "multiple byte
character set", right? :-) UTF-16 is an MSCS; multiple
short character set.
There appears to have been some discussion on 'tactis' and
'tactis260' earlier in bug 854511.

mbcs is only available on Windows.
I'm not sure what happened to the tactis codec - it's
possible that it never got checked in.
Do you have a reference for the tactis encoding ?
