kernel: look up ports when applying clock constraints. (#1448) 
prjunnamed does not emit a net alias for toplevel ports. This works
fine for constraining IOs but breaks clock constraints. This commit
expands clock constraint application code to look up net aliases first,
ports second.

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 43b2f38520 CMake: use imported target for pybind11. 
This accounts for the use of either the system or the vendored pybind11.

Fixes #1428.

Catherine 155adc3f5d CMake: rationalize and refactor build system. 
The two main changes, done together in this commit, are:
* Eliminating most instances of `aux_source_directory()`, replacing
  them with explicit file listings; and
* Moving these file listings into respective subdirectories by
  representing respective nextpnr components as interface libraries.

In addition, the GUI CMake script tree was simplified since it had
a lot of unused/redundant code.

The `aux_source_directory()` command is not recommended for use by
CMake itself because it misses dependency changes when adding/removing
files, and consequently causes build failures requiring a clean rebuild.

This commit does not touch anything related to architectures/families,
which are very complex and redundant all on their own.

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.
