Previously, in C++20 mode, using <=> on String8 or String16 would
compare the pointer values from the implicit conversion operators
returning const char* and const char16_t*. Instead, compare the string
content. This is especially a problem with STL containers that prefer
<=> when it is available.
See https://godbolt.org/z/cc1hW17h3 for a demo of the problem.

Dependencies of libbinder, so we can build
a core libbinder library, libbinder_sdk.
This is preparing the way to move this part of libbinder
together with binder code into a single project.
