Murisi/generalize vectorized transfers

[murisi]

Describe your changes

Attempt to simplify the combination of split MASP transfers and vectorized transfers. The main change is to make a transfer format that allows shielded operations to be done in the presence of both transparent inputs and transparent outputs. All the other transfer formats are then subsumed into this one.

Just a note: I think I've improved this in #3393 by trying to group the same sources/tokens before looking for the available notes

Closing in favor of #3459
