Merge remote-tracking branch 'origin/main' into fix/debug-execution-point-refresh

CMake run configurations used fixed arguments (-B build, Debug) and only recognised existing build directories.

Projects can now define CMake profiles under Settings › Build, Execution, Deployment › CMake: build type, generator, CMake arguments, build directory (default cmake-build-<type>), build arguments and environment. Each profile gets its own Configure, Build, CTest and target run configurations, named after the profile when there are several. Configure runs first only while the build directory has no CMakeCache.txt, and a generator change clears the stale cache before configuring. Projects without profiles keep the previous detection. Arguments are stored as lists and edited with the same quoting rules as program arguments. Toolchain selection is not part of this change.
