[Backend] Versal Support #73
Description
Support Versal next to Zynq and Alveo.
Zynq is currently targeted via the ZynqBuild -> MakeZYNQProject transformations.
Alveo is currently targeted via the VitisBuild -> VitisLink transformations.
The current plan would be to create additional VersalBuild/MakeVersalProject transformations that work similar to the current Zynq backend. We could then wrap all three platforms with a generic backend transformation that allows the user to select platform (Zynq, Alveo, Versal) and shell (e.g., IODMA, instrumentation, or both).
We could take inspiration from this Makefile-based flow for Versal that was never fully integrated into FINN: Xilinx#1082
