Roll libc++ from 8e870711923d to 9aaa9a2ee87b (231 revisions)

android-binary-size noticed that kAllowedWholeScriptConfusableWords
became a mutable constant in this roll, so following
docs/speed/binary_size/android_binary_size_trybot.md, section
"What to do if the Check Fails?", this explicitly masks that array
as constexpr (previously it was an array of mutable pointers pointing
to constant strings). Since the only user compares a u16string_view
to the entries, this also changes the type of the contents to
u16string_view.

Since this roll removes __LIBCPP_CONSTINIT but our libc++abi does
not yet have the change there to remove a use of it, this temporarily
adds a workaround to buildtools/third_party/libc++abi/BUILD.gn.
