While it served a purpose (granting the ability to build `.bba` files separately from the rest of nextpnr), it made things excessively convoluted, especially around paths. This commit removes the ability to pre-generate chip databases. As far as I know, I was the primary user of that feature. It can be added back if there is demand for it. In exchange the per-family `CMakeLists.txt` files are now much easier to understand.
