Use a sensible size for DSP to GUI MIDI messages

Browse Source 
See also a1ba561cc5. JACK2 and pipewire unconditionally
report 32kB, Ardour internal backends report 8kB, also
independent of the buffersize.
While jack1 by default announces the audio buffersize.

A sensible value assumes that the GUI reads the FIFO at
a least 25fps, while also allowing MIDI ports to merge
data (hence 2 * raw_buffer_size). Yet limit to 64k per track.
