Catherine d214308f5f CMake: reformat for consistency. 
Normalize keywords to:

    if (...)
    elseif (...)
    else()
    endif()

    foreach (...)
    endforeach()

    other(...)

Normalize whitespace to 4 spaces.

Catherine 574f504787 Find all components of Python at the same time. 
This is explicitly recommended by the FindPython module documentation
and is required to avoid failed builds on some systems. See:

YRabbit 90d4863dd4 gowin: Himbaechel. Add GW1NZ-1 BSRAM. 
The following primitives are implemented for the GW1NZ-1 chip:

* pROM     - read only memory - (bitwidth: 1, 2, 4, 8, 16, 32).
* pROMX9   - read only memory - (bitwidth: 9, 18, 36).
* SDPB     - semidual port    - (bitwidth: 1, 2, 4, 8, 16, 32).
* SDPX9B   - semidual port    - (bitwidth: 9, 18, 36).
* DPB      - dual port        - (bitwidth: 16).
* DPX9B    - dual port        - (bitwidth: 18).
* SP       - single port      - (bitwidth: 1, 2, 4, 8, 16, 32).
* SPX9     - single port      - (bitwidth: 9, 18, 36).

Also:
 - The creation of databases for GW1NS-2 has been removed - this was not
   planned to be supported in Himbaechel from the very beginning and
   even examples were not created in apicula for this chip due to the
   lack of boards with it on sale.
 - It is temporarily prohibited to connect DFFs and LUTs into clusters
   because for some reason this prevents the creation of images on lower
   chips (placer cannot find the placement), although without these
   clusters the images are quite working. Requires further research.
 - Added creation of ALU with mode 0 - addition. Such an element is not
   generated by Yosys, but it is a favorite vendor element and its
   support here greatly simplifies the compilation of vendor netlists.

Catherine eef5243fba himbaechel/gowin: recognize -DAPYCULA_INSTALL_PREFIX=.../virtualenv. 
This option can be empty, in which case the virtualenv is left
exactly as it was in the build environment.

YRabbit 98b09c369f gowin: Himbaechel. Fix the device selection 
Slightly change the Gowin device selection mechanism for database generation.
By default, nothing is generated as before.
