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. 2025-01-15 17:22:08 +08:00			`add_library(nextpnr_rust INTERFACE)`

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 2025-01-17 04:06:10 +08:00			`target_sources(nextpnr_rust INTERFACE rust.h)`
			`if (BUILD_RUST)`
			`target_sources(nextpnr_rust INTERFACE rust.cc)`
