tdf#104378: don't reset para attributes while

converting Chinese characters.

In TextConvWrapper::ChangeText_impl, calls to
EditView::RemoveAttribs() reset the paragraph attributes.
That makes SvxLanguageItem of EE_CHAR_LANGUAGE_CJK become
LANGUAGE_DONTKNOW. Hence it always stops converting after the
first success.

This patch overload EditView::RemoveAttribs() so that it is
possible to clear all character attributes of the selction
without touching paragraph attributes.

Before, bRemoveParaAttribs either removes items between
EE_ITEMS_START and EE_CHAR_END, or removes items between
EE_CHAR_START and EE_CHAR_END. The patch add a new enum
class EERemoveParaAttribsMode, with the following values:

1. RemoveAll : correspond to the old bRemoveParaAttribs = true
2. RemoveCharItems: correspond to the old bRemoveParaAttribs = false
3. RemoveNone: new thing for "don't touch para attributes."
