fix: handle string DRIVE property in pack_io without crashing (#1668) 
* fix: handle string DRIVE property in pack_io without crashing

The XDC parser stores all set_property values as string Properties,
but pack_io.cc called as_int64() on DRIVE which asserts !is_string.

Rather than converting numeric values to integer Properties in the
XDC parser (which risks breaking properties like LOC that downstream
code reads via to_string()/as_string()), fix the consumption site
in pack_io.cc to convert string values to integers when needed.

* refactor: use int_or_default for DRIVE property parsing

Replace manual is_string/as_int64 branching with int_or_default(),
which already handles both Property types with proper error reporting.

Catherine 90d746f79e CMake: add support for exporting and importing .bba files. 
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

Catherine cd7f7c12f1 CMake: refactor architecture-specific build system parts. 
Two user-visible changes were made:
* `-DUSE_RUST` is replaced with `-DBUILD_RUST`, by analogy with
  `-DBUILD_PYTHON`
* `-DCOVERAGE` was removed as it doesn't work with either modern GCC
  or Clang

Catherine dcfb7d8c33 CMake: align Himbaechel targets with non-Himbaechel ones. 
Primarily, this commit makes both of them use the `BBAsm` functions
to build and compile `.bba` files.

In addition, Himbaechel targets are now aligned with the rest in
how they are configured: instead of having all uarches enabled with
all of the devices disabled (the opposite of the rest of nextpnr),
uarches must be enabled explicitly but they come with all devices
enabled (except for Xilinx, which does not have a list of devices).

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

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

    foreach (...)
    endforeach()

    other(...)

Normalize whitespace to 4 spaces.

Various fixes for clang/libc++ build (#1415) 
* Gowin: add header includes required on libstdc++.

* kernel: fix incorrect printf-style format.

* himbaechel: add missing `override` qualifiers.

* Gowin: remove unnecessary `std::move`.

These calls inhibit RVO, a stronger optimization than moving an object.
