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.

Avoid calling constructors/destructors for
each element, when we have Vector<T*>. These
are used in libbinder and elsewhere.
std::vector is still faster but uses more mem.

A constexpr ctor is useful for static initialization.
We also modernize the unit test for static variable best practices.

Useful when dealing with raw pointers in unavoidable places. Avoids
an awkward (and "slow") dance of mySp->incStrong(0); mySp->get(); ~mySp;

This isolated all libutils_binder headers from libutils
except for RefBase use of CallStack.h. This header can
be disabled with a macro option easily.

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.
