media: v4l2-mem2mem: add new_frame detection

Commit f07602ac388723233e9e3c5a05b54baf34e0a3e9 upstream.

Drivers that support VB2_V4L2_FL_SUPPORTS_M2M_HOLD_CAPTURE_BUF
typically want to know if a new frame is started (i.e. the first
slice is about to be processed). Add a new_frame bool to v4l2_m2m_ctx
and set it accordingly.
