    Revert "tdf#120158: fix ImplGetParameterString for typename"
    
    This reverts commit 40e22f1e1bd44a1aa56ff77b82f1306ed1076ebf.  See the commit
    message of <https://gerrit.libreoffice.org/61684> "tdf#120158: Base
    CMimeContentType on INetMIME::scanContentType" why that change is considered a
    superior fix compared to the reverted one.

    tdf#120158: Base CMimeContentType on INetMIME::scanContentType
    
    ...instead of using yet another local implementation of parsing media types.
    
    CMimeContentType is the implementation of the UNO
    css.datatransfer.XMimeContentType interface.  One observable change in behavior
    is that type, subtype, and parameter names will now always be reported in lower
    case instead of with the casing from the input preserved (but those differences
    in casing are functionally equivalent per the media type specification).  Also,
    parameter names supplied to the hasParameter and getParameterValue functions are
    now also treated case-insensitive.
    
    The upside of this change is that INetMIME::scanContentType (via "The encoding
    of rMediaType should be US-ASCII, but any Unicode values in the range U+0080..
    U+FFFF are interpreted 'as appropriate.'") already implicitly supports RFC 6532
    "Internationalized Email Headers" extensions for media types, allowing quoted-
    string parameter values to contain non-ASCII Unicode characters.
    
    That means that tfd#120158 "Impossible to paste special in Writer from Calc in
    Libreoffice 6.1.x in some UI languages - the dialogue caption says 'unknown
    source'" can be fixed by just allowing non-ASCII typename parameters being
    generated in ImplGetParameterString in svtools/source/misc/transfer.cxx, and
    reverting the problematic (see the comments there) previous fix
    <https://gerrit.libreoffice.org/61601> "tdf#120158: fix ImplGetParameterString
    for typename".  (Which will be done in a follow-up commit, to ease potential
    backporting, as that previous fix has already been backported to some versions
    but not to others.)
