Drop o3tl/string_view.hxx

...now that all of its uses have been replaced with C++17 <string_view>.

The LO-specific o3tl::basic_string_view ctors with OString and OUString params
have meanwhile been replaced with OString and OUString conversion functions (in
dac7be50cff94e0c34cdca5ac7e35c19685c40c1 "o3tl::string_view -> std::string_view
(in configmgr)"), the ctor with OUStringLiteral turned out to be no longer(?)
needed anyway, and the LO-specific o3tl::toOUString has meanwhile been replaced
with an OUString ctor with std::u16string_view param (in
6856da30665705be6380e84cf55de954c41f15d1 "o3tl::string_view -> std::string_view
(in embedserv)").
