JNI: rename our compile-time String type to CTString

The type lives in the QtJniTypes namespace, which is where types end up
that are declared through the Q_DECLARE_JNI_CLASS/TYPE macros. Having a
String type in that namespace prevents us from declaring the Java String
class as a QtJniTypes type, which is silly.

Perhaps this type becomes obsolete at some point with std::string being
a constexpr type in C++23, but until then we need it. It has no ABI, so
renaming it us safe.

Until submodules are ported, leave a compatibility alias String type,
which also prevents us from declaring a String JNI class in tests until
the alias is removed in a later commit.
