Upgrade external/boost to Boost 1.69.0

<https://dev-www.libreoffice.org/src/boost_1_69_0.tar.bz2> is a copy of
<https://dl.bintray.com/boostorg/release/1.69.0/source/boost_1_69_0.tar.bz2>,
SHA256 hash as given at <https://www.boost.org/users/download/>.

* removed from external/boost/include/boost/ those files that are no longer
present in workdir/UnpackedTarball/boost/boost/

* the shrunk external/boost/rtti.patch.0 can probably be removed completely in a
follow-up commit

* the patch to libs/filesystem/src/operations.cpp in
external/boost/boost-android-unified.patch.1 no longer applied, and appears to
be no longer necessary anyway (seeing a working build without it of
--with-distro=LibreOfficeAndroid and NDK r16b); but with the non-standard
Clang 5.0.300080 from NDK r16b, the build now caused failures like

> workdir/UnpackedTarball/boost/boost/type_traits/detail/is_function_cxx_11.hpp:36:11: error: class template partial specialization contains a template parameter that cannot be deduced; this partial specialization will never be used [-Wunusable-partial-specialization]
>    struct is_function<Ret BOOST_TT_DEF_CALL(Args...)BOOST_TT_NOEXCEPT_DECL> : public true_type {};
>           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
> workdir/UnpackedTarball/boost/boost/type_traits/detail/is_function_cxx_11.hpp:35:38: note: non-deducible template parameter 'NE'
>    template <class Ret, class...Args BOOST_TT_NOEXCEPT_PARAM>
>                                      ^
> workdir/UnpackedTarball/boost/boost/type_traits/detail/is_function_cxx_11.hpp:22:40: note: expanded from macro 'BOOST_TT_NOEXCEPT_PARAM'
> #define BOOST_TT_NOEXCEPT_PARAM , bool NE
>                                        ^

showing that that version of Clang has the same problem handling noexcept(b)
as a deduced template parameter as MSVC has, as already supported by the code

* new external/boost/sse.patch.0 needed on Windows x86 to silence errors like

> C:\cygwin\home\tdf\lode\jenkins\workspace\gerrit_windows\workdir\UnpackedTarball\boost\boost/type_traits/detail/is_function_cxx_11.hpp(111): error C2215: '__vectorcall' cannot be used with '/arch:SSE'

(<https://ci.libreoffice.org/job/gerrit_windows/26117/>); according to
<https://docs.microsoft.com/en-us/cpp/preprocessor/predefined-macros
?view=vs-2017>: "_M_IX86_FP Defined as an integer literal value that indicates
the /arch compiler option that was set, or the default. This macro is always
defined when the compilation target is an x86 processor. Otherwise, undefined.
When defined, the value is: [...] 1 if the /arch:SSE compiler option was set."
and we specify /arch:SSE explicitly for Windows x86 since
8bd6bf93b7711a7ac7c5cbd7c3bb980481570ebd "fdo#82430: configure: MSVC build:
avoid using SSE2 instructions"

* boost::logic::tribool conversion operator to bool is explicit now
