Similar to gst_buffer_make_writable, but does not ensure that the buffer
data array is writable. Instead, this just ensures that the returned buffer
is solely owned by the caller, by creating a subbuffer of the original
buffer if necessary.
After calling this function, buf should not be referenced anymore. The
result of this function has guaranteed writable metadata.
