In O[U]StringBuffer, make string_view params replacements for OUString ones

...for LIBO_INTERNAL_ONLY, instead of having them as additional overloads.  That
way, loplugin:bufferadd and loplugin:stringviewparam found many further
opportunities for simplification (all addressed here).  Some notes:

* There is no longer an implicit conversion from O[U]String to O[U]StringBuffer
(as that goes via user-defined conversions through string_view now), which was
most noticeable in copy initializations like

OStringBuffer buf = someStr;

that had to be changed to direct initialization,

OStringBuffer buf(someStr);

But then again, it wasn't too many places that were affected and I think we can
live with that.

* I made the O[U]StringBuffer ctors taking string_view non-explicit, mainly to
get them in line with their counterparts taking O[U]String.

* I added an OUStringBuffer::lastIndexOf string_view overload that was missing
(relative to OUStringBuffer::indexOf).

* loplugin:stringconstant needed some addition to keep the
compilerplugins/clang/test/stringconstant.cxx checks related to
OStringBuffer::append and OStringBuffer::insert working.

* loplugin:stringviewparam no longer needs the special O[U]StringBuffer-related
code that had been introduced in 1250aecd71fabde4dba990bfceb61bbe8e06b8ea
"loplugin:stringviewparam extend to new.."
