CMake: add support for exporting and importing .bba files.

Browse Source 
This is useful for certain cross-compilation workloads, and to cache
rarely changing build products.

To use this functionality, build e.g. as follows:

    cmake . -B build-export -DEXPORT_BBA_FILES=../bba-files -DARCH=all
    cmake --build build-export -t nextpnr-all-bba

    cmake . -B build-import -DIMPORT_BBA_FILES=../bba-files -DARCH=all
    cmake --build build-import
