android: post_processor: Change the type destination in process()

The type of the destination buffer in PostProcessor::process() is
libcamera::Span. libcamera::Span is used for one dimension buffer
(e.g. blob buffer). The destination can be multiple dimensions
buffer (e.g. yuv frame). Therefore, this changes the type of the
destination buffer to MappedFrameBuffer.
