kleaf: Add -stdlib=libc++ -static-libstdc++ to host cc_* rules.

This is to ensure host toolchain can link to libc++
to build C++ code.

For compilation, this changes C++ code only; this
has no effect on C / assembly code.

For linking, this affects object files built from
both C / assembly code and C++ code.

This does not affect Kbuild, because
feature kleaf-host-cpp-ldflags and kleaf-host-cpp-flags
are disabled for kernel_* rules.

Using -static-libstdc++ removes the complication of adding
libc++ to runfiles for cc_binary, adjusting rpath, and
packaging libc++ along with the cc_binary when it is
mentioned in a pkg_* or copy_to_dist_dir rule.
