fdo#46193 MessBox was made copyable

Part of MultiLineEdit was moved down from stvools to vcl
with name VCLMultiLineEdit. MessBox uses it to display the
message in read-only mode. Some of svtools' classes - which
are necessary to implement VCLMultiLineEdit - were moved to
vcl as a whole, and their includes are rewrite.
Note: ExtTextView and ExtTextEngine classes would be leaved in svtools
if VCLMultiLineEdit is a template class, but two macros: IMPL_LINK
end IMPL_LINK_NOARG make it impossible to use template syntax.
