JNI: move private QJniObject helpers out of the public header

Browse Source 
Functions that are not called by any of the inline code don't have to be
in the public header. Move them as static functions into the translation
unit. Remove some useless wrappers in the private, and move the code for
private and static functions together.

Some private helpers have to stay in the ABI as they used to be called
by at least one public inline function up to Qt 6.6. Remove them from
the API using QT_CORE_REMOVED_SINCE.
